    lra: Ignore debug insns and notes in combine_reload_insn [PR109179]

    We ICE in combine_reload_insn if we've deleted the TO insn operand during
    processing, because lra_get_insn_recog_data doesn't expect to see the note
    that replaces the deleted insn.  The solution here is to exit early if TO
    is a debug insn or note.

            * lra-constraints.cc (combine_reload_insn): Enforce TO is not a
debug
            insn or note.  Move the tests earlier to guard
lra_get_insn_recog_data.
