This matches what GCC does in these situations. This fixes compiling Qt in debug mode. In release mode, references to the vtable of this particular class ends up optimized away, but in debug mode, the compiler creates references to the vtable, which is expected to be dllexported from a different DLL. Make sure the dllexported version actually ends up emitted. Differential Revision: https://reviews.llvm.org/D55698 llvm-svn: 349256
