[AMDGPU] Fix SIFoldOperandsImpl::tryFoldZeroHighBits when met non-reg src1 operand. (#133761)
This happens when a constant is propagated to a V_AND 0xFFFF, reg
instruction.
Fixes failures like:
```
llc: /github/llvm-project/llvm/include/llvm/CodeGen/MachineOperand.h:366: llvm::Register llvm::MachineOperand::getReg() const: Assertion `isReg() && "This is not a register operand!"' failed.
