    aarch64: Prevent moving throwing accesses in ldp/stp pass [PR113093]

    As the PR shows, there was nothing to prevent the ldp/stp pass from
    trying to move throwing insns, which lead to an RTL verification
    failure.

    This patch fixes that.

    gcc/ChangeLog:

            PR target/113093
            * config/aarch64/aarch64-ldp-fusion.cc (latest_hazard_before):
            If the insn is throwing, record the previous insn as a hazard to
            prevent moving it from the end of the BB.
