* Added extractLine line parsing to StringUtil. Use for matching lines instead of calcLines. calcLines uses extractLine to extract lines.
Fixed problems found in output of some tests- due to how a how final line is handled. Now a final line has a \r or \n\r combination, but nothing else after it, it is considered the last line (not the line after it).
* Use StringUtil::extractLine in slang-generate.
* Improved comment on extractLine
* Remove test code from StringUtil::extractLine
* Made StringUtil::extractLine act as if line terminators are 'separators'.
Added unit-test-string.cpp - to check behavior.

* Improved LineParser::Iterator end testing.
Added improved tests for LineParser.
* Move line comparson after termination case - to fix problem with gcc release build.
* Make UnownedStringSlice handle comparison when begin is nullptr - as it uses memcmp and passing nullptr to memcmp is undefined, leading to optimizer being able to do some unfortunate optimizations on gcc.

* Add a warning on missing return, and initial SCCP pass
The user-visible feature added here is a diagnostic for functions with non-`void` return type where control flow might fall off the end. This *sounds* like a trivial diagnostic to add as part of the front-end AST checking, but that can run afoul of really basic stuff like:
```hlsl
int thisFunctionisOkay(int a)
{
while(true)
{
if(a > 10) return a;
a = a*2 + 1;
}
// no return here!
}
```
This function "obviously" doesn't need to have a `return` statement at the end there, but realizing this fact relies on the compiler to understand that the `while(true)` loop can't exit normally, and doesn't contain any `break` statement. One can write "obvious" examples that need more and more complex analysis to rule out.
The answer Slang uses for stuff like this is to do the analysis at the IR level right after initial code generation (this would be before serialization, BTW, so that attached `IRHighLevelDeclDecoration`s can be used).
When lowering the AST to the IR, we always emit a `missingReturn` instruction (a subtype of `IRUnreachable`) at the end of its body if it isn't already terminated. The IR analysis pass to detect missing `return` statements is then as simple as just walking through all the functions in the module and making sure they don't contain `missingReturn` instructions.
For that simple pass to work, we first need to make some effort to remove dead blocks that control flow can never reach. This change adds a very basic initial implementation of Spare Conditional Constant Propagation (SCCP), which is a well-known SSA optimization that combines constant propagation over SSA form with dead code elimination over a CFG to achieve optimizations that are not possible with either optimization along.
For the moment, we don't actually implement any constant *folding* as part of the SCCP pass, so we can eliminate the dead block in a case like the function above (and those in the test case added in this change), but will not catch things like a `while(0 < 1)` loop. Handling more "obvious" cases like that is left for future work.
* fixup: warning on unreachable code
* Handle case where user of an inst isn't in same function/code
The code as assuming any instruction in the SSA work list has to come from the function/code being processed, but this misses the case where an instruction in a generic has a use inside the function that the generic produces.
This change adds code to guard against that case.

* Update glslang version
* Fix build for new glslang
The latest glslang required a few changes to our manual build for their code (because we are *not* taking a dependency on CMake).
* Rebuild project files using premake, which picks up a few files added to glslang, but also a few diffs in Slang's own project files in cases where they were edited manually instead of using premake.
* Fix up the declaration our our device limits (which are inentionally set to *not* limit what code passes through our glslang), because the underlying structure definition in glslang has changed. This is a kludgy bit of glslang's design, but it doesn't make sense for us to invest in a more serious workaround.
* Remove the "hack sampler" workaround
When the `GL_KHR_vulkan_glsl` spec was introduced to allow GLSL to be compiled for Vulkan SPIR-V, it made an annoying mistake by leaving a few builtins as taking `sampler2D`, etc. when the equivalent SPIR-V operations only require a `texture2D`, etc. The relevant builtins are:
* `textureSize`
* `textureQueryLevels`
* `textureSamples`
* `texelFetch`
* `texelFetchOffset`
This means that shader code that wanted to use those operations needed to conspire to have a `sampler` handy so they could write, e.g.:
```glsl
vec4 val = texelFetch(sampler2D(myTexture, someRandomSampler), p, lod);
```
when what they really wanted was this:
```glsl
vec4 val = texelFetch(myTexture, p, lod);
```
That is annoying but probably something each to work around for a GLSL programmer, but when cross-compiling from HLSL, you might have an operation like:
```hlsl
float4 val = myTexure.Load(p);
```
in which case a cross-compiler needs to manufacture a sampler out of thin air. If the shader happened to use a sampler for something else you could snag that, but in the worse case you had to cross-compile to GLSL that declared a new sampler.
Slang did this by declaring a sampler called `SLANG_hack_samplerForTexelFetch` (because `texelFetch` is the operation that first surfaced the issue). For complex reasons we *always* define this sampler, even if we turn out not to need it in a particular output kernel. This choice has a bunch of annoying consequences:
* There is *always* a sampler defined in descriptor set zero, because that's where we put the hack sampler, so a user-defined parameter block always has a set number of 1 or greater (see #646).
* The hack sampler shows up in reflection output because users need to size their descriptor sets appropriately to pass along this sampler that won't actually be used if they don't want to get debug spew from the validation layers.
We filed an issue on glslang about this problem, and eventually some kind folks from the gamedev community (who also saw the same problem) defined an extension spec (`GL_EXT_samplerless_texture_functions`) to fix the underlying issue and contributed a patch to glslang to make it support that extension.
This change just backs the hack out of Slang now that we have a glslang version that supports the extension to get past the defect in the original GLSL-for-Vulkan definition. Besides yanking out the code for the hack, we also change the relevant builtins to declare that they require this new GLSL extension (so that we properly request it from glslang when the builtins are used), and fix some reflection test cases that exposed the existence of the "hack sampler."
* Fixup: syntax error in stdlib generator files
* Remove more code for hack sampler
There was logic to ensure we always have a "default" register space/set when cross-compiling, because the hack sampler would need it. This is no longer necessary once we remove the hack sampler.
* Fix expected test output.
Fixing the root cause of issue #646 means that one of our test cases that tickles that issue now produces different output (luckily it can now be used as a regression test for the issue).

* Generate Visual Studio projects using Premake
This change adds a `premake5.lua` file that allows us to generate our Visual Studio solution using Premake 5 (https://premake.github.io/).
The existing Visual Studio solution/projects are now replaced with the Premake-generated ones, and project contributors will be expected to update these by running premake after adding/removing files.
I have *not* changed the Linux `Makefile` build at all, because that file is also used for things like running our tests, so that clobbering it with a premake-generated `Makefile` would break our continuous testing.
Hopefully future changes can switch to a generated `Makefile` and perhaps even add an XCode project as well.
Notes:
* The `build/slang-build.props` file is no longer needed/used, so it has been removed.
* The `slang-eval-test` test fixture wasn't following our naming conventions for its directory path, so it was updated to streamline the Premake build configuration work. This required changes to the `Makefile` as well
* Some seemingly unncessary preprocessor definitions that were specified for `core` and `slang-glslang` have been dropped. We will see if anything breaks from that.
* Possible fixup for Premake vpath issue
Premake's `vpath` feature seems to be nondeterministic about the order it applies filters (because Lua isn't deterministic about the order of entries in a key/value table), and as a result we can end up in a weird case where it decides that a `foo.cpp.h` file matches the `**.cpp` filter (I'm not sure why) before it tests against the `**.h` filter.
This change uses an (undocumented) Premake facility to set `vpath` using a list of singleton tables, which seems to fix the order in which things get tested.
* Remove support for "single-file" build of Slang
The `hello` example was the only bit of code that uses the "single-file" way of building Slang, and this had already run up against limitations of the Visual Studio compilers in its Debug|x64 build.
Rather than mess with Premake to make it pass through the `/bigobj` linker flag that is needed to work around the issue, it makes more sense just to stop using/supporting the feature since we wouldn't want users to depend on it anyway (our documentation no longer refers to it).
While I was at it I went ahead and made sure that the `SLANG_DYNAMIC` flag doesn't need to be set manually, so that instead there is a non-default `SLANG_STATIC` option (not that we have a static-library build of Slang at the moment).

* Dx12 rendering works in test framework.
* Turn on dx12 render tests.
* Getting simpler dx12 compute tests to work.
* With expected data in test - check for specialized and then for the default, so that multiple test can share the same expected data, but specialized cases can still be set.
* Fixed construction and binding on dx12 textures.
* Control which render apis used in test from command line.
* Small aesthetic fixes in render-test/main.cpp.
* Fix binding problem for uavs/srvs dx12. Previously tried to create srv/uav for StorageBuffers (like dx11 does), but the binding breaks as you can end up with two srvs using the same register.
First pass at fixing problems with Texture creation for dx12 - assertions were hit with 3d or array textures.
* Fixes to improve Dx12 setup shader resource views for cubemaps/arrays.
* Fixed d3d12 textureSamplingTest - problem was that cubemap/array textures were not being uploaded correctly.
* Changed the order of how binding of constant buffers (as just set on the Renderer) indexes. Previously they were given the lowest indices, but they clashed with the indices from the 'Binding'. Changing this means all tests run on d3d12.
* Add code to allow use of warp (although not command line switchable yet).
Fix problem setting up raw UAV - as identified by warp.
* Added RenderApiUtil - which can detect if a render api is potentially available.
* Moved render flag testing/parsing into RenderApiUtil.
* Fix signed/unsigned warning.
* Fixes around enums prefixed with k on the review of feature/dx12 compute branch.

Fixes #350
When the Slang project forked off from the Spire research effort, we renamed things as we went, but many cases seem to have slipped through the cracks.
The two biggest diffs here are:
- The `hello` example program was incorrectly talking about what was in the shader file (Slang no longer supports the "module" or "pipeline" constructs from Spire), and so it wasn't just a simple rename.
- The files under `tests/bindings` were mistakenly using `__SPIRE__` as a preprocessor guard, which means that they weren't actually testing what they meant to. Luckily, it looks like the relevant functionality didn't regress while these tests were unintentionally deactivated.
