KRM7 0926d94453 [GlobalISel] Take the result size into account when const folding icmp (#134365) ...

The current implementation always creates a 1 bit constant for the
result of the `G_ICMP`, which will cause issues if the destination
register size is larger than that. With asserts enabled, it will cause a
crash in `buildConstant`:
```
llvm/lib/CodeGen/GlobalISel/MachineIRBuilder.cpp:322: virtual MachineInstrBuilder llvm::MachineIRBuilder::buildConstant(const DstOp &, const ConstantInt &): Assertion `EltTy.getScalarSizeInBits() == Val.getBitWidth() && "creating constant with the wrong size"' failed. 
```
