4037 of bitnum rather than offset, bitpos and byte_offset. Move the

4039 the TMODE-based mode_for_size calculation succeeds. Split the
4040 plain move cases into two, one for memory accesses and one for
4041 register accesses. Generalize the memory case, freeing it from
4042 the old register-based endian checks. Move the INT_MODE calculation
4043 above the code that needs it. Use simplify_gen_subreg to handle

4046 that both targets and register sources fit within a word.
