This has gotten updated - some key things:
- The current design on the langAS -> TargetAS conversion is currently inspired by our CXXABILowering. They serve different purposes but the intention remained the same. We need to rewrite all ops that may hold pointer types with an AS qualifier, that's our intrinsic legalization condition.

This branch is fairly outdated (I think CI might be failing due to that) so I'll rebase it when https://github.com/llvm/llvm-project/pull/179082 lands.
