[modules] Be sure to emit local specializations of imported templates, even if the resulting specialization is not referenced by the rest of the AST. This both avoids performing unnecessary reinstantiations in downstream users of the AST file and fixes a bug (breaking modules self-host right now) where we would sometimes fail to emit a definition of a class template specialization if we imported just a declaration of it from elsewhere (see new testcase for reduced example). llvm-svn: 283489 2016-10-07 04:30:51 +08:00			`// RUN: rm -rf %t`
