Ben Clayton c41c7cdf31 reader/wgsl: Only resync if num errors less than limit
As all loops in the parser require `synchronized_` to be true, don't set this to true if we've hit the maximum number of error diagnostics.
This lets the parser bubble up as soon as the limit was reached, instead of only aborting once we finally reach the top level loop.

ClusterFuzz has uncovered a number of cases where, in a loop, it can produce an error, then resynchronize, then error again on the next loop iteration. This produces more than the max limit of errors, and can stall the tests long enough to time out.

No unit tests for this, as it requires a really contrived input to trigger, and to exhaustively catch all the places we now call maybe_set_synchronized() would result in a large colleciton of horrible tests. Instead, let ClusterFuzz do the testing.

Ben Clayton f24b37e122 writer/msl: Rework string printing
Add `out` parameters to expression and type generators.

Use the new helper classes in TextGenerator.
Cleans up bad formatting.

Prepares the writer generating 'pre' statements, required for atomics.

If-else statements are generated slightly differently. This is done so that 'pre' statements for the else conditions are scoped correctly. This is identical to the HLSL writer.

Vasyl Teliman 0b3611b8c8 Add spirv-tools fuzzer
This change adds a new tint fuzzer that uses SPIRV-Tools to fuzz SPIR-V binaries.
The fuzzer works on a corpus of SPIR-V shaders. For each shader from the corpus it uses
one of `spirv-fuzz`, `spirv-reduce` or `spirv-opt` to mutate and then runs the shader through
the Tint compiler in two steps:
- Converts the mutated shader to WGSL.
- Converts WGSL to some target language specified in the CLI arguments.

The list of all supported CLI arguments and their description is in the cli.h file.

Also validate that builtin/location decorations are not used on

Fix or delete all of the other tests that were wrongly using these

David Neto 7aac7b521e spirv-reader: Handle vector insert dynamic into a hoisted variable
VectorInsertDynamic normaly inserts a temporary variable.
But if the source vector is already a hoisted variable, then
reuse that instead.  This avoids defining the same name twice.

Use a DisableValidationDecoration to allow these storage classes only

Fix or delete all of the tests that were wrongly using these storage
classes.

David Neto 53a0d2681a spirv-reader: Handle composite insert into a hoisted variable
Composite insert normally inserts a temporary variable.
But if the composite value is already a hoisted variable,
then reuse that instead.  This avoids defining the same name twice.

Also add AddressOfIfNeeded and use it when processing the operand
of an OpCopyObject or when making a let-declaration. Only take the
address in these cases when the corresponding SPIR-V type is a
pointer.

David Neto 3d5453ce9c spirv-reader: remove builtin-inputs special cases
Remove special case handling of pointers and values related
to builtins SampleId, VertexIndex, and InstanceIndex.
These map to private variables with store type matching the
type stated in the SPIR-V code. There is no need to generate
special case code for user-written functions accessing those variables.

Therefore:
- Remove SkipReason enums associated with those builtin inputs
- Remove newly unreachable code.
