This implements a proposal by Doug Gregor on cfe-dev a couple of years ago, to allow the compiler to emit strong symbols for explicit template instantiations. Doug's spec, which I have tried to follow can be found here: http://lists.llvm.org/pipermail/cfe-dev/attachments/20111203/5e1c6c35/attachment.html. I usually work over in LLVM-land and have only contributed the occasional bug fix to clang, so please let me know how this patch can be improved. I'm also not fully done testing it yet (only did so on the toy example I included as a test case), but I wanted to get this out there to get feedback.
