877df9e4 - [SelectionDAG] Make SSHLSAT/USHLSAT obey getShiftAmountTy(). (#173216)

[SelectionDAG] Make SSHLSAT/USHLSAT obey getShiftAmountTy(). (#173216) Treat these like other shift operations by allowing the shift amount to be a different type than the result. The PromoteIntOp_Shift and LegalizeDAG code are not tested due to lack of target support. I'm looking at adding SSHLSAT for the RISC-V P extension. I don't need this support for that since RISC-V only has one legal type. I just thought it was odd that they weren't like other shifts.
