Codegen using SPIRV-LLVM Translator regressed #349
Description
As part of JuliaGPU/GPUCompiler.jl#709 I contemplated (temporarily) reverting back to the SPIRV-LLVM-Translator, which luckily seems to support our new SPIRV Intrinsics (i.e. the format is compatible with both back-ends), but a couple of tests seem to have regressed:

It would be good to fix that and maybe add a CI job so that we keep supporting both (for the time being).
