4142 of bitnum rather than offset, bitpos and byte_offset. Move the

4144 the TMODE-based mode_for_size calculation succeeds. Split the
4145 plain move cases into two, one for memory accesses and one for
4146 register accesses. Generalize the memory case, freeing it from
4147 the old register-based endian checks. Move the INT_MODE calculation
4148 above the code that needs it. Use simplify_gen_subreg to handle

4150 directly to extract_split_bit_field. Assume after that point
4151 that both targets and register sources fit within a word.
