  [RISCV] Use COPY to create artificial 64-bit uses in RISCVOptWInstrs's tests

In reflection of 4dd5d967975fa8d52b8c60596d892d9dd5615809, we can now
use COPY to physical registers to create artificial 64-bit uses to
prevent RISCVOptWInstrs from optimizing away sext in absent of the
IsSignExtendingOpW flag.
