This register is only supported on the powerpcspe targets. It is only recognized by LLVM. gcc does not accept this as a clobber, nor does it support these targets.

This is a volatile register, thus it is included with clobber_abi.

Allow PowerPC spe_acc as clobber-only register

This register is only supported on the *powerpc*spe targets. It is only recognized by LLVM. gcc does not accept this as a clobber, nor does it support these targets.
