register accesses.  Generalize the memory case, freeing it from

above the code that needs it.  Use simplify_gen_subreg to handle
multiword OP0s.  If the field still spans several words, pass it
directly to extract_split_bit_field.  Assume after that point
that both targets and register sources fit within a word.
Replace x-prefixed variables with non-prefixed forms.
