I tried to look, and see only case of `Z_R14` seems valid. Because that is the exception there (volatile and sandwiched between saved registers). In Float & Vector registers we have "almost" continuous register, except `Z_F1` but there `is_volatile()` method will do no good, because `Z_F1` is indeed volatile and not used by Register Allocator. So I dropped the use for `is_volatile()`. And kept the changes same.
