[AMDGPU] Add llvm.amdgpu.update.dpp intrinsic Summary: Now that we've made all the necessary backend changes, we can add a new intrinsic which exposes the new capabilities to IR producers. Since llvm.amdgpu.update.dpp is a strict superset of llvm.amdgpu.mov.dpp, we should deprecate the former. We also add tests for all the functionality that was added in previous changes, now that we can access it via an IR construct.
