[PATCH] D35558: Use sys::Memory::AllocateRWX for JIT code

Keep in mind that the SELinux case in libffi is not fork-safe. One important part LLVM needs to consider is
whether it wants to enshrine the performance penalty of mprotect-after-commit in its APIs or not. The second part
is whether platforms should aim to support hot-patchable JIT for multi-threaded environments or not. If the latter is
not considered relevant, the API only needs to provide a function to allocate JIT-safe memory and a function to make
it executable. If the latter is relevant, the current AllocateRWX is the interface you will end up with, one way or the other.
