Summary: This was a lot of code that was only used for upstream LLVM builds of AMDGPU offloading. We have a generic and fast `malloc` in `libc` now so just use that. Simplifies code, can be added back if we start providing alternate forms but I don't think there's a single use-case that would justify it yet.
