When building a vector via tint::writer::AppendVector, and the
vector argument is already a vector constructor, expand that
vector constructor into its components only when those components
are all scalars. This avoids a type breakage which can occur with cases
like this:
vector argument is:
vec2<i32>(vec2<u32>(0u,1u))
scalar argument is:
2
Before this fix, the result was:
vec2<i32>(0u, 1u, 2);
But should be this instead:
vec3<i32>(vec2<u32>(0u,1u),2)
This was noticed in SPIR-V writer output when forming a coordinate
vector from a an unsigned WGSL coordinate vector with a signed array
vector.

This code was implicitly assuming that all resources it was looking
for would be directly referenced at the intrinsic callsite, and not
passed via function parameters.
This was causing a crash in more complex cases.
The inspector code has been updated to handle cases where the
resources are not being directly referenced.
Unneeded calls to GenerateSamplerTargets() are removed.
Utility function GetOriginatingResources() is added to handle walking up
call sites to resolve resources.
Text shader based test runner is added to the Inspector tests to make
expressing complex tests easier.

The continuing block can exit the loop in very constrained ways:
When a break statement is placed such that it would exit from a loop’s
§ 7.3.8 Continuing Statement, then:
- The break statement must appear as either:
- The only statement in the if clause of an if statement that has:
- no else clause or an empty else clause
- no elseif clauses
- The only statement in the else clause of an if statement that has an
empty if clause and no elseif clauses.
- That if statement must appear last in the continuing clause.
By design, this allows a lossless round-trip from SPIR-V to WGSL and
back to SPIR-V. But that requires this special case construct in WGSL
to be translated to an OpBranchConditional with one target being
the loop's megre block (which is where 'break' branches to), and the
other targets the loop header (which is the loop backedge). That
OpBranchConditional takes the place of the normal case of an
unconditional backedge.
Avoids errors like this:
continue construct with the continue target X is not
post dominated by the back-edge block Y

This adds SPIR-V assembly and WGSL tests derived from VK-GL-CTS commit
571256871c2e2f03995373e1e4a02958d8cd8cf5. The following procedure was
followed:
- Those .amber files in VK-GL-CTS wholly owned by Google were
identified
- All GLSL and SPIR-V shaders were extracted from the Amber files and
converted into SPIR-V binaries
- The compact-ids pass of spirv-opt was applied to each binary
- Duplicate binaries were removed
- spirv-opt -O was used to obtain an optimized version of each remaining
binary, with duplicates discarded
- Binaries that failed validation using spirv-val with target
environment SPIR-V 1.3 were discarded
- Those binaries that tint could not successfully convert into WGSL were
put aside for further investigation
- SPIR-V assembly versions of the remaining binaries are included in
this CL
- test-runner with -generate-expected and -generate-skip was used to
generate expected .spvasm, .msl, .hlsl and .wgsl outputs for these
SPIR-V assembly tests
- Each successfully-generated .expected.wgsl is included in this CL
again, as a WGLSL test
- test-runner with -generate-expected and -generate-skip was used again,
to generate expected outputs for these WGSL tests

The SPIR-V Tools fuzzer asserts that the binaries it receives have sizes
that are multiples of 4 bytes, as it should only ever run on valid
binaries. This is failing in ClusterFuzz, likely due to the fuzzer being
misconfigured, so for now these assertions have been replaced with early
exits. They should be reinstated once the fuzzer is correctly
configured.
