fold-const: Don't access bit fields with too big mode (PR71310)
Currently, optimize_bit_field_compare reads the bitfield in word_mode
if it can. If the bit field is normally accessed in a smaller mode,
this might be a violation of the memory model, although the "extra"
part of the read is not used. But also, previous stores to the bit
field will have been done in the smaller mode, and then bigger loads
from it cause a LHS problem.

Remove word_mode hack for split bitfields
This patch is effectively reverting a change from 1994. The reason
I think it's a hack is that store_bit_field_1 is creating a subreg
reference to one word of a field even though it has already proven that
the field spills into the following word. We then rely on the special
SUBREG handling in store_split_bit_field to ignore the extent of op0 and
look inside the SUBREG_REG regardless. I don't see any reason why we can't
pass the original op0 to store_split_bit_field instead.
Tested on aarch64-linux-gnu and x86_64-linux-gnu.
gcc/
* expmed.c (store_bit_field_1): Do not restrict a multiword op0
to one word if the field is known to overlap other words.
(extract_bit_field_1): Likewise.
(store_split_bit_field): Remove compensating code.
(extract_split_bit_field): Likewise.
