Move builtin must_use tests into per-builtin validation suites

1

We have tests that the results of most builtins must be used in [must_use.spec.ts](https://github.com/gpuweb/cts/blob/main/src/webgpu/shader/validation/parse/must_use.spec.ts), but we have also started adding equivalent tests inside the per-builtin validation suites, e.g. #3496. We...

Add more cases to canvas reftest with device loss

limit the overrides in the shader interface, to those that are "statically accessed"

2

The definition of "statically accessed" is now recursive in more interesting ways, to make sure it pulls in the right set of overrides. https://github.com/gpuweb/gpuweb/pull/3600

wgsl: & and * are lower precedence than .member and [], even in LHS

2

This was already true for general expressions. https://github.com/gpuweb/gpuweb/pull/3582 fixed it for LHS. So now: ```rust fn foo { var a: array; *&a[0] = 1; // This is fine. Parses as...

wgsl: test smoothstep early evaluation error when low >= high

1

The spec has been updated https://github.com/gpuweb/gpuweb/pull/4616 If low >= high, it's a shader-creation error if both are const-expressions. it's a pipeline-creation error if both are override-expressions (and not const-expressions). Note...
