Log:
        PR target/81325
        * cfgbuild.c (find_bb_boundaries): Ignore debug insns in decisions
        if and where to split a bb, except for splitting before debug insn
        sequences followed by non-label real insn.  Delete debug insns
        in between basic blocks.

        * g++.dg/cpp0x/pr81325.C: New test.
