LoongArch: Add CRC expander to generate faster CRC
64-bit LoongArch has native CRC instructions for two specific
polynomials. For other polynomials or 32-bit, use the generic
table-based approach but optimize bit reversing.
gcc/ChangeLog:
* config/loongarch/loongarch.md (crc_rev<mode:SUBDI>si4): New
define_expand.
