test: add a test for windows itanium exceptions Some time ago, I noticed that try would get resolved incorrectly for Windows Itanium targets. Add an explicit test to exsure that exceptions are handled correctly for Windows Itanium environments. llvm-svn: 211992

Set dso_local on external rtti GVs. In this particular case it would be possible to just add an else with CGM.setDSOLocal(GV), but it seems better to have as many callers as possible just call setGVProperties so that we can centralize the logic there. This patch then makes setGVProperties able to handle null Decls. llvm-svn: 327543
