5268 (extract_bit_field_1): Remove unit, offset, bitpos and
5269 byte_offset from the outermost scope. Express conditions in terms
5270 of bitnum rather than offset, bitpos and byte_offset. Move the
5271 computation of MODE1 to the block that needs it. Use MODE unless
5272 the TMODE-based mode_for_size calculation succeeds. Split the
5273 plain move cases into two, one for memory accesses and one for
5274 register accesses. Generalize the memory case, freeing it from
5275 the old register-based endian checks. Move the INT_MODE calculation
5276 above the code that needs it. Use simplify_gen_subreg to handle
5277 multiword OP0s. If the field still spans several words, pass it
5278 directly to extract_split_bit_field. Assume after that point
5279 that both targets and register sources fit within a word.
