MS ABI: Records with required alignment can't have common linkage This fixes PR22441. llvm-svn: 227950

MS ABI: Aligned tentative definitions don't have CommonLinkage int __declspec(align(16)) foo; is a tentative definition but the storage for that variable should not have CommonLinkage. llvm-svn: 214828

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
