dcd2b082 - [RISCV] Use FSHR in LowerShiftRightParts for P extension on RV64. (#181234)

[RISCV] Use FSHR in LowerShiftRightParts for P extension on RV64. (#181234) We can't do the NSRLI trick on RV64, but we can use srx similar to what we do in LowerShiftLeftParts. We need an additional fixup step for the FSHR result that NSRLI doesn't need. Assisted-by: claude
