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.
Issue: #2346
The web/emscripten build has been broken for an unknown amount of time
and for multiple reasons:
- Calling `cat` on Windows
- The latest version of wasm-ld does not support the `--no-undefined`
flag
- `ccall` was not being exported
Fixes#3272.
Currently with the build instructions provided in README.md
the build will fail.
In the r25 NDK the CMake toolchain defaults to the legacy path,
due to a bug in the current implementation.

The 'set' and 'setRT' variables were warning as maybe-uninitialized even
though in practice that case would never trigger (due to how the
function flow-controls).
The code blocks where these variables are actually read do not overlap,
so merge them into the same 'set' variable.
Simplify the control flow of the function with early-returns, which
drops indentation and simplifies the function.
Ensure we traverse the entire tree and upgrade all references to the
given symbol so it can be upgraded to push_constant. Without this change
only one instance was upgraded, and others were left as uniform buffers.
Previously, spirv_type doesn't accept type specifier as its parameter.
With this change, we can input non-array type specifier. This is because
some SPIR-V type definition intructions often need to reference other
SPIR-V types as its source operands. We add the support to facilitate
such usage.
Vertex shaders can have pipeline inputs that are arrays, but not structure
inputs. (GLSL 4.5 section 4.3.4)
But the error message for struct inputs says "cannot be a structure or array".
This PR removes the "or array" part.
Note: The array case is handled immediately after the check for
structure type.

spirv_decorate_id will generate OpDecorateId. The parameter list should
accept variables as part of decorations. This is because OpDecorateId
allows this. The spec says:
All such <id> Extra Operands must be constant instructions or
OpVariable instructions.
This adds a new fullyExpanded flag that makes sure that macro arguments
only get expanded once. This can happen either in PrescanMacroArg, or, if
there is token pasting or a function-like macro name has been passed as
an argument and may need to be expanded when used as a function.

Using LLONG_MIN instead avoids the problem. I think it's also more
clear, and the code for EOpMod further down already does this.
From TParseContext used only by GLSL, to TParseContextBase inherited by both GLSL and HLSL paths.
It caused compilations from HLSL to SPIR-V 1.3+ to use BufferBlock decoration which is no longer valid.
GLSL 1.20 and prior stated that "the attribute qualifier can be used
only with float, floating-point vectors, and matrices" and likewise
for varying.
Fixes: #3111
