PR target/71677
* config/rs6000/constraints.md (wY constraint): New constraint to
match the requirements for the LXSD and STXSD instructions.
* config/rs6000/predicates.md (offsettable_mem_14bit_operand): New
predicate to match the requirements for the LXSD and STXSD
instructions.
* config/rs6000/rs6000.md (mov<mode>_hardfloat32, FMOVE64 case):
Use constaint wY for LXSD/STXSD instructions instead of 'o' or 'Y'
to make sure that the bottom 2 bits of offset are 0, the address
form is offsettable, and no updating is done in the address mode.
(mov<mode>_hardfloat64, FMOVE64 case): Likewise.
(movdi_internal32): Likewise
(movdi_internal64): Likewise.
