* A new approach to AST serialization
This change completely overhauls the way that AST nodes are being serialized, and the offline source-code generation steps that enable that serialization.
In practice, this ends up being a complete overhaul of the way that *modules* are being serialized (not just the AST part), although things like the serialization format for the Slang IR and for source locations are not affected.
The rest of this commit message is broken down in to sections, in an attempt to help guide anybody looking at the code in how to make sense of all the changes.
The Old C++ Extractor
---------------------
AST serialization used to be driven by information scraped using the `slang-cpp-extractor` tool, which did an ad hoc parse of the C++ declarations of the AST node types and then generated a set of "X macros" that could be for macro-based code generation within the rest of the compiler.
While the existing approach was functional, it wasn't easy to understand or maintain, and it has been getting in the way of forward progress on other features we'd like to work on in the language and compiler.
This change removes the `slang-cpp-extractor` tool entirely.
Marking Up the AST Declarations
-------------------------------
The most notable change that contributors to the compiler may notice is the large number of invocations of a macro `FIDDLE()` on the declarations of the AST node types.
The basic idea is that only declarations (namespaces, types, fields) that are preceded by `FIDDLE()` are visible to the code generator tool.
So if somebody is working with the AST and wondering why a new node type isn't working, or why a field they added isn't being serialized correctly, it is probably because they need to add `FIDDLE()` in front of it.
Generating the Boilerplate Code
-------------------------------
The file `slang-ast-boilerplate.cpp` provides a good example of how the information extracted from the marked-up AST declarations gets used.
In that file, the `FIDDLE TEMPLATE` construct is used to generate type information for each of the AST node types.
Similar logic is used in `slang-ast-forward-declarations.h` to generate the declaration of the `ASTNodeType` enumeration, and forward-declare all the AST node classes.
For many parts of the code, simply including that file replaces the need for the old `slang-generated-*.h` files.
Replacing Visitors and Related Logic
------------------------------------
The old visitor types for the AST used the macros that were generated by `slang-cpp-extractor`, so something new was needed to replace them.
The same goes for the `SLANG_AST_NODE_VIRTUAL_CALL` macros.
The core of the solution implemented here is in `slang-ast-dispatch.h`.
Given a "dispatchable" AST node type (say, `Expr`), a call like:
```
ASTNodeDispatcher<Expr,R>(expr, [&](auto e) { return doSomething(e); })
```
is an expression of type `R`, which does the equivalent of something like:
```
switch(expr->getTag())
{
case ASTNodeType::VarExpr: return doSomething(static_cast<VarExpr*>(expr));
// ...
}
```
The `SLANG_AST_NODE_VIRTUAL_CALL` macro is now implemented in terms of `ASTNodeDispatcher`.
The implementation of the visitor types is more involved.
The code in this change retains some of the macro names from the original version, just to try and make the parallels more clear.
The visitor types are all implemented on top of the `ASTNodeDispatcher` approach, and use `FIDDLE TEMPLATE` to generate all the boilerplate `visit*()` method declarations.
Refactoring of `Linkage` Module Loading
---------------------------------------
Needing to revisit all the places where modules get deserialized made it clear that there is a lot of complexity and apparent duplication in the core routines on the `Linkage` that get used for loading modules.
This change tries to clean up some of that logic, but it is worth noting that there are two legacy features that get in the way of making things as clean as they should be:
* The `LoadedModuleDictionary` type that gets passed around a lot exists entirely to handle the corner case where somebody uses the Slang API to perform a compilation with multiple `TranslationUnitRequest`s in the same `FrontEndCompileRequest`, and one of the translation units `import`s the module defined by another of the translation units.
* There are a lot of special-case behaviors and routines entirely there to support the `ModuleLibrary` feature, although that feature should be considered deprecated (or at least subject to getting entirely re-designed down the line).
The basic idea of the cleanup is that all of the (non-deprecated) ways load a module from a serialized binary, or compile one from source should now bottleneck through `loadModuleImpl`, which then bifurcates into `loadSourceModuleImpl` for the compilation case and `loadBinaryModuleImpl` for the deserialization case.
High-Level Serialization Approach
---------------------------------
The old serialization logic used the [RIFF](https://en.wikipedia.org/wiki/Resource_Interchange_File_Format) format to encode the high-level structure of things, and this change retains that usage (and actually doubles down on the RIFF usage).
The old serialization system relied on the idea that for any given type `Foo` that wants to support serialization, there should be something like a `SerialFooData` type in C++, that can represent the state of a `Foo`, and then the actual serialization applied to that `SerialFooData`. This means that in most cases there are four pieces of code written:
* During serialization:
* Copying the data of a `Foo` in memory over to a `SerialFooData` in memory
* Writing the state of a `SerialFooData` into the serialized data stream
* During deserialization:
* Reading the state of a `SerialFooData` from a serialized data stream
* Copying the data of the `SerialFooData` in memory over to a `Foo`
The new logic gets rid of the intermediate `SerialFooData`.
In the serialization direction, we take a `Foo` and write it to the `RIFFContainer` directly, or using some other utilities layered on top of it.
In the deserialization direction, we have additional flexibility. Given a `RIFFContainer::Chunk*` that represents a serialized `Foo`, we often navigate through the in-memory representation of the RIFF data to get to the parts of the serialized value that we actually want/need, without needing to deserialize the entire `Foo`.
To support this kind of operation, this change introduces a few helper types like `ContainerChunkRef` an `ModuleChunkRef`, that are little more than typed wrappers around a `RIFFContainer::Chunk*`.
The Module "Container" Part
---------------------------
A serialized `Module` is encoded as a RIFF chunk, using logic in `slang-serialize-container.cpp` - both before and after this change.
This change reorganizes a lot of the code in that file, to account for the way that eliminating the intermediate `SerialContainerData` type streamlines the overall task of writing out the parts of the module.
In the deserialization logic... there isn't really much to do in `slang-serialize-container.cpp`. Most of the logic in `slang.cpp` and `slang-module-library.cpp` that pertains to deserializing modules uses the `ModuleChunkRef`-based approach, and simply extracts the pieces of the serialized module that it needs.
The Actual Serialization of the AST
-----------------------------------
The actual AST serialization logic is in `slang-serialize-ast.cpp`.
The basic approach in both the writing and reading directions is:
* Use the `FIDDLE TEMPLATE` system to generate a set of functions, one for each AST node type, that recursively invoke the read/write logic on each field of that node (after recursively invoking the case for its direct superclass)
* Use the `ASTNodeDispatcher` system to dispatch out to those functions whene reading or writing anything derived from `NodeBase`
* For now, handle all types *not* derived from `NodeBase` by hand.
There's a lot of room for improvement around that last item: it should be just as easy to generate the serialization and deserialization logic for other types that don't inherit from `NodeBase`, but the current change tries to err on the side of making the logic as explicit and simplistic as possible, rather than trying to get too clever too soon.
The actual serialization *format* used for the AST is almost comically simplistic: the code uses hierarchical RIFF chunks to emulate a JSON-like structure. This is a very wasteful representation (e.g., a `bool` or a null pointer each take up *8 bytes*), but the goal for now is to start with the simplest thing that could possibly work, and only add more cleverness once we are sure it won't get in the way of important future improvements (like lazy/on-demand deserialization or IR and AST, to improve compiler startup times).
The files `slang-serialize.{h,cpp}` have been co-opted to define a new pair of types `Encoder` and `Decoder` that are used for a more-or-less stream-oriented way or reading or writing RIFF chunks for the JSON-like structure.
Almost everything related to the actual AST serialization could do with a cleanup pass, and some time spent on picking good/better names for everything.

* Move the file public header files to `include` dir
Close the issue (#4635).
Move the following headers files to a `include` dir
located at root dir of slang repo:
slang-com-helper.h -> include/slang-com-helper.h
slang-com-ptr.h -> include/slang-com-ptr.h
slang-gfx.h -> include/slang-gfx.h
slang.h -> include/slang.h
Change cmake/SlangTarget.cmake to add include path to
every target, and change the source file to use
"#include <slang.h>" to include the public headers.
The source code update is by the script like follow:
```
fileNames_slang=$(grep -r "\".*slang\.h\"" source/ -l)
for fileName in "${fileNames_slang[@]}"
do
echo "$fileName"
sed -i "s/\".*slang\.h\"/\"slang\.h\"/" $fileName
done
```
* Fix the test issues
* Fix cpu test issues by adding include seach path
* Update cmake to not add include path for every target
Also change "#include <slang.h>" to "include "slang.h" " to
make the coding style consistent with other slang code.
* Change public include to private include for unit-test and slang-glslang

* Overhaul the preprocessor
The old Slang preprocessor was based on a simple mental model that tried to unify two parts of macro expansion:
* Scanning for macro invocations in a sequence of tokens
* Producing the expanded tokens for a macro expansion by substituting arguments into its body
The basic was that substitution of macro arguments into a macro definition is superficially similar to top-level macro expansion, just with an environment where the macro arguments act like `#define`s for the corresponding parameter names. That approach was "clever" and could conceivably have been extended to include a lot of advanced preprocessor features (e.g., a preprocessor-level `lambda` would be easy to support!), but it was basically impossible to make it correctly handle all the corner cases of the full C/C++ preprocessor.
The fundamental problem with the old approach was that it conflated the two parts of expansion listed above into one implementation, while the various special cases of the C/C++ preprocessor rely on treating the two cases very differently. The new approach here (which is somewhere between a refactor and a full rewrite of the preprocessor) changes things up in a few key ways:
* The abstraction still cares a lot about streams of tokens, but it now treats the top level streams (`InputFile`s) as fairly different from the lower-level streams (`InputStream`s)
* Macro expansion is handled as a dedicated type of stream that wraps another stream. This allows macro expansion to be applied to anything, and supports cases where multiple rounds of macro expansion are required by the spec.
* Macro *invocations* and the substitution of their arguments are now handled by a completely new system.
* Macro arguments are no longer treated as if they were `#define`s
* The macro body/definition is analyzed at definition time to detect various kinds of issues, and to derive a list of "ops" that make it easier to "play back" the definition at substitution time
* Token pasting and stringizing are now only handled in macro definitions (rather than being allowed anywhere), and their use cases are restricted to only those that make sense (e.g., you can't stringize anythign except a macro parameter, because anything else wouldn't make sense)
The key new types here are the `ExpansionInputStream` which handles scanning for macro invocations, and the `MacroInvocation` type, which handles playing back the macro body with substitutions.
The `ExpansionInputStream` is the easier of the two to understand. By refactoring it to use a single token of lookahead, the one major detail it had to deal with before (abandoning expansion of a function-like macro if the macro name was not followed by `(`) is significantly easier to manage.
The more subtle part is the `MacroInvocation` type, and most of the complexity there is around handling of token pasting, and the fact that either or both of the operands to a token paste might be empty.
Many of the test cases that exposed the problems in the preprocessor have been moved from `current-bugs` to `preprocessor` since they now work correctly.
