This significantly simplifies the calling code from Dawn.
It does require moving the SingleEntryPoint transform above the
renamer, since we need to call SEP with the original name. That is
probably also an optimization, since we do the subsequent transforms

This toggle controls if the fuzzer will throw a fatal error in the
case that the shader becomes invalid.
Currently the fuzzers do no guarantee that the options that are
provided are correct/valid, so there are many uninteresting cases that
become invalid due to the limited nature of the fuzzers, not due to
bugs in the code. The default off state of this toggle will suppress
this noise.
Once https://bugs.chromium.org/p/tint/issues/detail?id=1356 is
implemented this toggle can be default on.

This is a check that has been added to newer versions of clang and is

Updating protobufs has cross-dependency issues with spriv-tools, so is

protobuf issues, so I am just adding to the carve out.

In GLSL, gl_SampleID and gl_SampleMask[In] require the
GL_OES_sample_variables extension, so output:
"#extension GL_OES_sample_variables : require"
in the header if those builtins is used.
Note that extensions must be inserted before the default precision
declaration, but helpers must be inserted after it, so we set a flag
and emit extensions, then the precision declaration, then helpers.
Further fixes:
- use gl_SampleMaskIn for input builtins, gl_SampleMask for output,
necessitating the addition of a storage class to GLSLBuiltinToString()
- fix the handling of gl_SampleMaskIn: it's array<i32> in GLSL, not
array<u32> as in SPIR-V
- centralize conversions for GLSL builtins used as input variables in
FromGLSLBuiltin()
- implement bitcasts on assignment to GLSL builtin output variables,
centralized in ToGLSLBuiltin()
- update the extension handling in the GLSL writer to check for both
sample_index and sample_mask.
- call UnwrapRef() in GLSL's EmitBitcast(). In the test case, we were
not recognizing the argument as a uint, yielding float() instead of
uintBitsToFloat().
