    [PR104971] LRA: check live hard regs to remove a dead insn

    LRA removes insn modifying sp for given PR test set.  We should also have
    checked living hard regs to prevent this.  The patch fixes this.

    gcc/ChangeLog:

            PR middle-end/104971
            * lra-lives.cc (process_bb_lives): Check hard_regs_live for hard
            regs to clear remove_p flag.
