* Remove the "VM" and "bytecode" features
The "bytecode" in `bc.{h,cpp}` was an initial attempt at a serialized encoding for the Slang IR, but we now have the `ir-serialize.{h,cpp}` approach which was has been kept up to date much better.
Similarly, the "VM" in `vm.{h,cpp}` was intended to be a system for interpreting Slang code in the bytecode format directly (so that you could load and evaluate code in a Slang module in a lightweight fashion). This never got used past a single test, which we eventually disabled.
There are good ideas in some of this code, but at this point the implementations have bit-rotted to a point where trying to maintain it is more costly than it would be to re-created it if/when we ever decide these features are important again.
* fixup: remove slang-eval-test from Makefile

being null is defined as undefined behavior in the standard. This is a workaround that disables that optimization for now. (#708)

* 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).

* Remove support for the -no-checking flag
Fixes #381
Fixes #383
Work on #382
- No longer expose flag through API (`SLANG_COMPILE_FLAG_NO_CHECKING`) and command-line (`-no-checking`) options
- Remove all logic in `check.cpp` that was withholding diagnostics (including errors) when the no-checking mode was enabled
- Remove `HiddenImplicitCastExpr`, which was only created to support no-checking mode (it represented an implicit cast that our checking through was needed, but couldn't emit because it might be wrong)
- Remove logic for storing function bodies as raw token lists when checking is turned off. I'm leaving in the `UnparsedStmt` AST node in case we ever need/want to lazily parse and check function bodies down the line.
- Remove a few of the code-generation paths we had to contend with, but keep the comment about them in place.
- Remove GLSL-based tests that can't meaningfully work with the new approach.
- Fix other tests that used a GLSL baseline so that their GLSL compiles with `-pass-through glslang` instead of invoking `slang` with the `-no-checking` flag.
- Remove tests that were explicitly added to test the "rewriter + IR" path, since that is no longer supported.
There is more cleanup that can be done here, now that we know that AST-based rewrite and IR will never co-exist, but it is probably easier to deal with that as part of removing the AST-based rewrite path.
We've lost some test coverage here, but actually not too much if we consider that we are dropping GLSL input anyway.
* Fixup: test runner was mis-counting ignored tests
* Fixup: turn on dumping on test failure under Travis
* Fixup: enable extensions in Linux build of glslang

* Attempt to fix subprocess handling for Linux
Our CI builds are sometimes hanging on Travis, and I suspect it might be something to do with how we are waiting for subprocesses to complete. I'm trying to following the manpage for the `wait()` and `waitpid()` calls a bit better here.
* fixup: try to use poll() instead of select()
* fixup: missing header
* fixup
* fixup
* fixup: try to emit test output when tests fail on Travis

* Get tests running/passing under Linux
- Fix up `dlopen` abstraction
- Fix up some test cases to request hlsl (rather than default to dxbc) so they can run on non-Windows targets
- Fix up test runner ignore tests that can't run on current platform (and not count those as failure)
- Fix file handle leeak in process spawner absttraction
- Get additional test-related applications building
- More tweaks to Travis script; in theory deployment is set up now (yeah, right)
* fixup
* fixup: Travis environment variable syntax
* fixup: Buffer->begin
* fixup: actually run full tests on one config
* fixup: add build status badge for Travis

* First attempt at a Linux build
- Fix up places where C++ idioms were written assuming lenient behavior of Microsoft's compiler
- Add a few more alternatives for platform-specific behavior where Windows was the only platform accounted for.
- Add a basic Makefile that can at least invoke our build, even if it isn't going good dependency tracking, etc.
- Build `libslang.so` and `slangc` that depends on it, using a relative `RPATH` to make the binary portable (I hope)
- Add an initial `.travis.yml` to see if we can trigger their build process.
* Fixup: const bug in `List::Sort`
I'm not clear why this gets picked up by the gcc *and* clang that Travis uses, but not the (newer) gcc I'm using on Ubuntu here, but I'm hoping it is just some missing `const` qualifiers.
* Fixup: reorder specialization of "class info"
Clang complains about things being specialized after being instantiated (implicilty), and I hope it is just the fact that I generate the class info for the roots of the hierarchy after the other cases. We'll see.
* Fixup: add `platform.cpp` to unified/lumped build
* Fixup: Windows uses `FreeLibrary`
and not `UnloadLibrary`
* Fixup: fix Windows project file to include new source file
This obviously points to the fact that we are going to need to be generating these files sooner or later.
