    rtl-ssa: Provide easier access to debug uses [PR113089]

    This patch adds some accessors to set_info and use_info to make it
    easier to get at and iterate through uses in debug insns.

    It is used by the aarch64 load/store pair fusion pass in a subsequent
    patch to fix PR113089, i.e. to update debug uses in the pass.
