2040 of bitnum rather than offset, bitpos and byte_offset. Move the
2041 computation of MODE1 to the block that needs it. Use MODE unless
2042 the TMODE-based mode_for_size calculation succeeds. Split the
2043 plain move cases into two, one for memory accesses and one for
2044 register accesses. Generalize the memory case, freeing it from
2045 the old register-based endian checks. Move the INT_MODE calculation
2046 above the code that needs it. Use simplify_gen_subreg to handle
