[PATCH] D52977: [RISCV] Introduce codegen patterns for instructions introduced in RV64I

Updated to fix a PatFrags-related assertion and to add exhaustive testing for the *W instruction patterns. Although verbose, these tests have shown their worth by 1) identifying a missing pattern which I've now added and 2) flagging a few cases where codegen could be improved in future.
