I rebased and resolved conflicts just now and got the compiler built. I did not update the tests, hence not updating this review. I see the following outstanding issues:

(1) make check-libomptarget produces a bunch of failures with the following compile-time assertion. So my rebased patch is not interacting correctly with opaque pointers. It is the same assertion for all the failures.
llvm-project/llvm/include/llvm/IR/Type.h:384: llvm::Type* llvm::Type::getNonOpaquePointerElementType() const: Assertion `NumContainedTys && "Attempting to get element type of opaque pointer"' failed.

(2) From earlier investigation a couple of months back, this patch uses device alloc and will fail if device allocation is not implemented (e.g. in main branch of amdgpu). Most of these failures are seen at -O0, OpenMPOpt is able to optimize them away at higher opt levels. Are we ok with these failures at -O0?

(3) There were a few issues found regarding SPDMization, NoCaptureAttrs, alignment that should be applied to this patch. I have those changes on a local branch.
