[clang] [HIP][AMDGPU] Use non-LTO pipeline for non-RDC in the linker wrapper (PR #201135)

This compiles the files individually, which somewhat works, but if you use libraries you'll end up with object linking. Might be fine for compiler-rt because I think the function resource usage is smaller than an indirect call, but it'll be slow.
