[RISCV] Add test cases that show failure to use some W instructions if they are proceeded by a load. NFC
The loads end up becoming sextload/zextload which prevent our isel patterns from finding the sign_extend_inreg or AND instruction we need. The easiest way to fix this is to use computeKnownBits or ComputeNumSignBits in our isel matching to catch this.
