LoongArch: NFC: Deduplicate crc instruction defines

Introduce an iterator for UNSPEC_CRC and UNSPEC_CRCC to make the next
change easier.

gcc/ChangeLog:

	* config/loongarch/loongarch.md (CRC): New define_int_iterator.
	(crc): New define_int_attr.
	(loongarch_crc_w_<size>_w, loongarch_crcc_w_<size>_w): Unify
	into ...
	(loongarch_<crc>_w_<size>_w): ... here.
