HeCBench/HIP pass rates on slightly not-up-to-date version of the patch with https://github.com/KhronosGroup/SPIRV-LLVM-Translator/pull/3940 incorporated to SPIR-V consumer are on par with and without `SPV_KHR_untyped_pointers` extension. I'll re-run the suite, but as of now I believe the PR is ready for review.
