4731 Allow simplify_gen_subreg to fail rather than calling validate_subreg.
4732 Move the handling of multiword OP0s after the code that coerces VALUE
4733 to an integer mode. Use simplify_gen_subreg for this case and assert
4734 that it succeeds. If the field still spans several words, pass it
4735 directly to store_split_bit_field. Assume after that point that
4736 both sources and register targets fit within a word. Replace
4737 x-prefixed variables with non-prefixed forms. Compute the bitpos
4738 for insv register operands directly in the chosen unit size, rather
4739 than going through an intermediate BITS_PER_WORD unit size.
4740 Update the call to store_fixed_bit_field.
4741 (store_fixed_bit_field): Replace the bitpos and offset parameters
4742 with a single bitnum parameter, of the same form as store_bit_field.
4743 Assume that OP0 contains the full field. Simplify the memory offset
4744 calculation. Assert that the processed OP0 has an integral mode.
4745 (store_split_bit_field): Update the call to store_fixed_bit_field.
