This reverts commit r260449. We would supress our emission of vftable definitions if we thought another translation unit would provide the definition because we saw an explicit instantiation declaration. This is not the case with dllimport, we want to synthesize a definition of the vftable regardless. This fixes PR26569. llvm-svn: 260548
