Implemented preserves_flags on powerpc by making it do nothing. This prevents having two different ways to mark `cr0` as clobbered. clang and gcc alias `cr0` to `cc`. The gcc inline documentation does not state what this does on powerpc* targets, but inspection of the source shows it is equivalent to condition register field `cr0`, so it should not be added.
