    debug/112718 - reset all type units with -ffat-lto-objects

    When mixing -flto, -ffat-lto-objects and -fdebug-type-section we
    fail to reset all type units after early output resulting in an
    ICE when attempting to add then duplicate sibling attributes.

            PR debug/112718
            * dwarf2out.cc (dwarf2out_finish): Reset all type units
            for the fat part of an LTO compile.

            * gcc.dg/debug/pr112718.c: New testcase.
