PR22877: When constructing an array via a constructor with a default argument in list-initialization, run cleanups for the default argument after each iteration of the initialization loop. We previously only ran the destructor for any temporary once, at the end of the complete loop, rather than once per iteration! Re-commit of r302750, reverted in r302776. llvm-svn: 302817

Bring r325915 back. The tests that failed on a windows host have been fixed. Original message: Start setting dso_local for COFF. With this there are still some GVs where we don't set dso_local because setGVProperties is never called. I intend to fix that in followup commits. This is just the bare minimum to teach shouldAssumeDSOLocal what it should do for COFF. llvm-svn: 325940
