5867 of bitnum rather than offset, bitpos and byte_offset. Move the

5869 the TMODE-based mode_for_size calculation succeeds. Split the
5870 plain move cases into two, one for memory accesses and one for
5871 register accesses. Generalize the memory case, freeing it from
5872 the old register-based endian checks. Move the INT_MODE calculation
5873 above the code that needs it. Use simplify_gen_subreg to handle
