Log Message:
-----------
[WGSL] webgpu:shader,validation,uniformity,uniformity:* is failing
https://bugs.webkit.org/show_bug.cgi?id=309199
rdar://171757884
Reviewed by Mike Wyrzykowski.
Introduce the UniformityAnalysis pass that verifies whether the shader satifies
the uniformity rules according to the spec[1]. The pass builds a control flow
graph and uses the algorithm outline in section 15.2.3.
