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.
