    [RISCV] Fix PR 106632 and PR 106588 a few constraints in bitmanip.md
    
    The constraints should be n instead of i. Also there
    needs to a check for out of bounds zero_extract for
    *bexti.
    
    gcc/ChangeLog:
    
            PR target/106632
            PR target/106588
            * config/riscv/bitmanip.md (*shNadduw): Use n constraint
            instead of i.
            (*slliuw): Likewise.
            (*bexti): Likewise. Also add a check for operands[2] to be less
            than the mode bitsize.
