        extract_fixed_bit_field.  In the big-endian case, always
        use the mode of OP0 to count the number of significant bits.
        (extract_bit_field_1): Remove unit, offset, bitpos and
        byte_offset from the outermost scope.  Express conditions in terms
        of bitnum rather than offset, bitpos and byte_offset.  Move the
        computation of MODE1 to the block that needs it.  Use MODE unless
        the TMODE-based mode_for_size calculation succeeds.  Split the
        plain move cases into two, one for memory accesses and one for
        register accesses.  Generalize the memory case, freeing it from
        the old register-based endian checks.  Move the INT_MODE calculation
        above the code that needs it.  Use simplify_gen_subreg to handle
        multiword OP0s.  If the field still spans several words, pass it
        directly to extract_split_bit_field.  Assume after that point
        that both targets and register sources fit within a word.
        Replace x-prefixed variables with non-prefixed forms.
        Compute the bitpos for ext(z)v register operands directly in the
        chosen unit size, rather than going through an intermediate
        BITS_PER_WORD unit size.  Simplify the containment check
        used when forcing OP0 into a register.  Update the call to
        extract_fixed_bit_field.
        (extract_fixed_bit_field): Replace the bitpos and offset parameters
        with a single bitnum parameter, of the same form as extract_bit_field.
        Assume that OP0 contains the full field.  Simplify the memory offset
        calculation and containment check for volatile bitfields.  Make the
        offset explicit when volatile bitfields force a misaligned access.
        Remove WARNED and fix long lines.  Assert that the processed OP0
        has an integral mode.

        Allow simplify_gen_subreg to fail rather than calling validate_subreg.
        Move the handling of multiword OP0s after the code that coerces VALUE
