Use relative include paths in StandAlone/ResourceLimits.h

Switched to std::string for TReflection and TObjectReflection

Port Unix/ossource.cpp to Fuchsia

Fix a couple of warnings clang found

Disable Clang extra semicolon warning.

In MSVC 2017 Debug mode when a reflection is deleted (when a shader goes out of scope) xutility will fail to clear the children due to the TString allocator implementation. By switching to std::string xutility no longer throws the error.

Fuchsia has pthreads but doesn't have sys/resource.h and doesn't
implement pthread_cleanup_push().

ANGLE bug: 2475

Usually this warning is disabled by default. But when turned on Clang
complains about extra semicolons in Glslang headers. Turn this off for
now. See http://crbug.com/926235

Add support for GL_EXT_YUV_target

Hopefully, this fixes the sudden new breakage with the bots.

Reflection consistency changes & bugfixes

* Previously the offset was only updated with EOpIndexDirectStruct, but we also
  need to update it for the other index types into arrays, and when expanding an
  aggregate reached after dereferencing.

Update spirv-tools known-good.

build: Do not cache debug library suffix

For nested project builds, writing CMAKE_DEBUG_POSTFIX into the cache
ends up affecting other projects. Caching this value doesn't seem to be
required in practice, so this change removes the cache tag.

Suppress a MSVC cast warning in GN.

Also came up when using the BUILD.gn file with ANGLE.

ANGLE bug: 3088

Add extension checks for NV block member builtins

Suppress inconsistent override warning in GN.

This came up when trying to roll the new glslang into Chromium.

ANGLE bug: 3088

Infrastructure: Generalize and broaden per-variable extension checking.

Fix a few GN build issues.

More precisely check for the qualifiers that enable the vulkan memory model for buffer references.

Not all memory qualifiers necessarily need the vulkan memory model, e.g. volatile/restrict that correspond to core SPIR-V features do not.

 * adds a source set for default resource limits to mirror CMake
 * adds a target executable for the standalone validator
 * fixes a missing warning

Allows ANGLE to use the integrated BUILD.gn instead of a custom one.
