d5666294 - [RISCV] Porting hasAllNBitUsers to RISCV GISel for instruction select (#125795)

[RISCV] Porting hasAllNBitUsers to RISCV GISel for instruction select (#125795) Ported hasAllNBitUsers to RISCV GISel side. Add GISelPredicate code to each of the 16,32, and 64 bit words. It allows for generation of optimized packw sequences along with other transparent narrowing operations. Included a few new .ll files to expand testing and limited the OptW pass Optimization to fewer options until GISel is ready for more code generation paths --------- Signed-off-by: Luke Quinn <quic_lquinn@quicinc.com>
