LoongArch: Prevent subreg of subreg in CRC
The register_operand predicate can match subreg, then we'd have a subreg
of subreg and it's invalid. Use lowpart_subreg to avoid the nested
subreg.
gcc/ChangeLog:
* config/loongarch/loongarch.md (crc_combine): Avoid nested
subreg.
gcc/testsuite/ChangeLog:
* gcc.c-torture/compile/pr120708.c: New test.
