[LoongArch] Add remaining intrinsics for CRC check instructions

[gonglingqin]

Summary

After D137316 implements the intrinsics of the first crc check instruction
and related diagnosis, this patch implements the intrinsics of all remaining
crc check instructions.

Can we define a marco but not repeating similar codes?
For example:

#define CRC_CASE(NAME, ISD) \
    case Intrinsic::loongarch_#NAME: { \
      Results.push_back(DAG.getNode( \
          ISD::TRUNCATE, DL, VT, \
          DAG.getNode(LoongArchISD::#ISD, DL, MVT::i64, \
                      DAG.getNode(ISD::ANY_EXTEND, DL, MVT::i64, Op2), \
                      DAG.getNode(ISD::ANY_EXTEND, DL, MVT::i64, Op3)))); \
      Results.push_back(N->getOperand(0)); \
      break; \
    }

Then

CRC_CASE(crc_w_b_w, CRC_W_B_W)

Address @SixWeining's comments.

LGTM.

You could use uppercase to keep consistency.

llvm/lib/Target/LoongArch/LoongArchISelLowering.cpp

Thanks, I will modify it.

Address @SixWeining's comments.

otherwise LGTM

What's a "two op", are you meaning "binary op" instead?

942

Similarly, is this actually "unary op"?

[gonglingqin]

llvm/lib/Target/LoongArch/LoongArchISelLowering.cpp

925–952

Yes, thank you for your correction!

942

Thanks a lot! I will modify it.

Seems the difference is not binary op or unar op. They are both binary ops. The difference is that the former uses 2 ISD::ANY_EXTEND while the latter only use one.
