This makes us emit dllexported in-class initialized static data members (which are treated as definitions in MSVC), even when they're not referenced. It also makes their special linkage reflected in the GVA linkage instead of getting massaged in CodeGen. Differential Revision: http://reviews.llvm.org/D4563 llvm-svn: 213304
