The current implementation makes tests fail when it is imported from a
different Bazel workspace. We fix that by using
the --test-root flag to pass the rootpath to the
tests.
We need separate concepts for
- total set of extensions ever enabled, for the back end
- current state of extensions, for parsing
- the set of features currently enabled for building the AST
This detangles incorrect conflation of HLSL with GLSL extensions,
defers asking expensive questions until it's time to ask, and removes
some dead code.
The scalar type was already the basic type passed in.
Also factored out of this the checking of extensions for 8/16-bit stuff.
This code seems wrong in several ways, but for now just documenting it.
This change strips a few features similar to GLSLANG_WEB but doesn't
remove every detail like the latter. It also hardcodes profile/version
to core/450.
In particular, TBuiltIns::initialize is specialized to remove most of
what is not supported or won't be supported by ANGLE. The result of
this function is parsed with TParseContext::parseShaderStrings which is
a performance bottleneck.
This change shaves about 300KB off of ANGLE's binary size and reduces
the cost of SetupBuiltinSymbolTable to nearly a sixth.

iOS 8 does not support `thread_local`, which is still in use.
Another approach will have to be found.
This change is a revert of the following changes:
a3845240 - "Simplify PoolAlloc with use of thread_local."
abf92c80 - "Deprecate InitializeDll functions"
33585c87 - "Limit visibility of symbols for internal libraries"

Also remove `SPIRV/doc.cpp` from the `SPVRemapper` target as this
is part of `SPIRV`, causing ODR violations. Instead have
`SPVRemapper` link against `SPIRV`.
Fixes ODR violations.
glslang is using C++ 11, which has first class support for variables of the `thread_local` storage class.
By dropping the use of the `OS_[GS]etTLSValue`, we can simplify the logic, and have it support a thread-local default allocator if none is provided.

when traversing the AST to find live UBOs etc, also traverse
references to global module-level variables, incase they are
being filled in from UBOs etc.
