[turbofan] Also allow TaggedSigned/Pointer memory operand. When we added the new MachineRepresentation::kTaggedSigned and MachineRepresentation::kTaggedPointer, we didn't extend the logic for memory operand covering, and so for map checks and other comparisons with fields we'd always need an additional register. This fixes that and does reduce register pressure in some cases.
