    rtl-optimization/119689 - compare-debug failure with LRA

    The previous change to fix LRA rematerialization broke compare-debug
    for i586 bootstrap.  Fixed by using prev_nonnote_nondebug_insn
    instead of prev_nonnote_insn.

            * lra-remat.cc (create_cands): Use prev_nonnote_nondebug_insn
            to check whether insn2 is directly before insn.

            * g++.target/i386/pr119689.C: New testcase.
