This is a modified version of the HLSL writer.
Basic types, arrays, entry points, reserved keywords, uniforms,
builtin uniforms, structs, some builtin functions, zero initialization
are implemented. Textures, SSBOs and storage textures in particular are
unimplemented. All the unit tests "pass", but the output is not correct
in many cases.
triangle.wgsl outputs correct vertex and fragment shaders that pass
GLSL validation via glslang. compute_boids.wgsl outputs a valid but not
correct compute shader.

An assertion failure had been injected to check that black box fuzzing
is working, but as ClusterFuzz runs a release mode build this was not
triggering. This change turns the assertion failure into an abort. Once
it has been established that the abort is triggered by the black box
fuzzers, it should be removed.

When preparing a corpus of SPIR-V shaders for fuzzing, spirv-as is
invoked repeatedly. It could be that a bug in spirv-as leads to
conversion failing for some of the shaders. This should not prevent the
overall corpus from being generated, as long as the number of overall
failures is reasonably small. This change adds some tolerance for such
failures.

This makes it possible to build the fuzzer in Chromium's asan builder
group by having it depend on the tint fuzzers group, and means that the
logic for when particular fuzz targets are built remains encapsulated in
the tint fuzzer build rules.

Use a threadgroup memory argument for any workgroup variable that
contains a matrix.
The generator now provides a list of threadgroup memory arguments for
each entry point, so that the runtime knows how many bytes to allocate
for each argument.

Dawn needs to know if a given entry point uses this builtin, so that
it can pass this information via a root constant for HLSL.

For HLSL, use the new NumWorkgroupsFromUniform transform, and expose
the binding point to use for the generated uniform as a backend
option.
The MSL mapping is trivial, and it was already implemented for WGSL
and SPIR-V.

This transform scans entry points for struct parameters that contain
the num_workgroups builtin, and replace accesses to these members with
a value loaded from a uniform buffer.
This will be used by the HLSL backend to implement the num_workgroups
builtin.
