Build fails due to external dependency on SPIRV-Tools.
EX:
```
-- Looking for pthread_create in pthread
-- Looking for pthread_create in pthread - found
-- Found Threads: TRUE
CMake Error at External/spirv-tools/CMakeLists.txt:15 (cmake_minimum_required):
CMake 3.17.2 or higher is required. You are running version 3.14.0
```
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.
There was a race condition in this function as it used a static variable
to attempt to ensure global initialization was only done once, which was
not thread-safe. Instead, use std::call_once, which was added to C++11
for this exact case.
Fixes#342
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.
From the command line, the debug options "stack", with -gVS enabling all
of generateDebugInfo, emitNonSemanticShaderDebugInfo and
emitNonSemanticShaderDebugSource, however the programmatic interface
allows setting the latter options without the former. In this case, the
string corresponding to the source filename never gets emitted and some
debuginfo instructions end up with zero ID operands, resulting in
invalid SPIR-V.
Fixes#3240
The `function` parameter is only used by an assert currently, so mark
it as "maybe unused". Alternatively the parameter could be removed,
but avoid such API churn for now.
The FindPythonInterp and FindPythonLibs modules, which have
been deprecated since CMake 3.12, have been removed by policy
CMP0148. Port projects to FindPython3, FindPython2, or FindPython.
The containsPhysicalStorageBufferOrArray function now handles struct
types correctly, checking their contents recursively for buffer
reference types. As a result, OpVariables containing structs that have
members that are buffer references now have the appropriate
AliasedPointer or RestrictPointer decoration as per the spec.
Fixes#3188
