5277 byte_offset from the outermost scope. Express conditions in terms
5278 of bitnum rather than offset, bitpos and byte_offset. Move the
5279 computation of MODE1 to the block that needs it. Use MODE unless
5280 the TMODE-based mode_for_size calculation succeeds. Split the
5281 plain move cases into two, one for memory accesses and one for
5282 register accesses. Generalize the memory case, freeing it from
5283 the old register-based endian checks. Move the INT_MODE calculation
5284 above the code that needs it. Use simplify_gen_subreg to handle
