Yes, I think this might be useful for the compiler to have this extra bits in, even though it was agreed originally not to add it. I think it was considered as something that is not absolutely necessary to have.

Would your change be aligned with SPIR 2.0 as asked during the previous discussion here:

I'd like to add pipe packet size and alignment information to LLVM IR as pipe built-in function parameters as defined in SPIR 2.0 provisional specification<https://www.khronos.org/registry/spir/specs/spir_spec-2.0.pdf>.

Previous discussion on this topic can be found in the review comments here: https://reviews.llvm.org/D15914.

Any objections/comments?
