This is useful in order to identify codegen issues caused by SIMD32. It doesn't currently have any effect on compute shaders since SIMD32 dispatch is only enabled for CS when it's strictly necessary to do so in order to support the workgroup size requested for the shader -- That might change in the future though when we hook up the SIMD32 heuristic to CS compilation.
