[Patch AArch64] Warn on unpredictable stlxrb , stlxrh and stlxr cases.
A recent case in golang highlighted that gas wasn't warning on these
unpredictable cases in the architecture. Fixed thusly.
I need to audit gcc to make sure we have early clobbers on the
patterns but that's a separate patch.
Tested aarch64-none-elf and gas
Ok ?
