According to the extension SPV_GOOGLE_decorate_string,
OpDecorateString (or OpMemberDecorateString) ought to be capable of
supporting multiple literal strings. Each literal strings are padded
with null terminator to make word alignment. The layout is:

  Inst | Target | Decoration | Literal String, Literal String, ...

Error when initializing rayQuery with assignment

Parser: Fix wrong names of extension macros

SPIRV: Fix some disassembly issues

- OpExecutionModeId is not supported in disassembly.
- Some execution modes are missing in disassembled strings.

The names of some extension macros are wrong because of coding typos.

Suppress two override suggestion warnings.

We're turning these on in ANGLE and want to keep the build clean.

This reverts commit f257e0ea, reversing
changes made to 8f0c6bd7.

Obey ENABLE_PCH CMake option

Use --test-root to pass files to Bazel tests.

GLSLANG_EXPORT for C APIs.

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.

Remove incorrect style of extension-based semantic checking.

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.
