[X86] Transform `(cmp eq/ne trunc(X), C)` -> `(cmp eq/ne X, Zext(C))`

[goldstein.w.n]

Summary

This previously existed for C == 0, but is mostly beneficial for any
C.

There is a slight codesize cost as we get more imm32 (as opposed to
imm8) constants in some cases. But the benefit is was get less imm16
constants (LCP stalls) and save instructions in some vec -> scalar
codegen.

Should add non-zero tests?

cast

[goldstein.w.n]

dyn_cast -> cast

It felt like we saw enough changes throughout CodeGen/X86/ that it was sufficient. But if you prefer
I can add some new explicit tests for it.

LGTM - we might want to consider a DAGISel peephole to take of cases where we lose signextended imm8 values.

DAGISel? Which file is that? X86ISelDAGToDAG.cpp?

[goldstein.w.n]

use auto

Assume that.

I tried:

EVT OpVT = N0.getValueType();
if (OpVT.isScalarInteger() && OpVT.getScalarSizeInBits() > 8 &&
    !isNullConstant(N1)) {
  const APInt &C = cast<ConstantSDNode>(N1)->getAPIntValue();
  if (C.getSignificantBits() <= 8 &&
      CurDAG->MaskedValueIsZero(
          N0, APInt::getBitsSetFrom(OpVT.getScalarSizeInBits(), 8))) {
    SDValue TruncN0 = CurDAG->getZExtOrTrunc(N0, dl, MVT::i8);
    insertDAGNode(*CurDAG, SDValue(Node, 0), TruncN0);
    SDValue TruncN1 = getI8Imm(C.truncSSat(8).getZExtValue(), dl);
    insertDAGNode(*CurDAG, SDValue(Node, 0), TruncN1);
    SDValue NewCmp =
        CurDAG->getNode(X86ISD::CMP, dl, MVT::i32, TruncN0, TruncN1);
    ReplaceNode(Node, NewCmp.getNode());
    if (N1.getNode()->use_empty())
      CurDAG->RemoveDeadNode(N1.getNode());
    SelectCode(NewCmp.getNode());
    return;
  }
}

In X86ISD::CMP handling of select but fail in X86InstrInfo::analyzeCompare
with:

MachineOperand.h:370: llvm::Register llvm::MachineOperand::getReg() const: Assertion `isReg() && "This is not a register operand!"' failed.

See anything obviously wrong in home I'm setting this up?

Thanks @goldstein.w.n - I've raised https://github.com/llvm/llvm-project/issues/62312 to discuss this
