Log:
Add extern template instantiations of llvm::Calculate.

This should be a small build time improvement in general and fixes
the build on OS X with -DBUILD_SHARED_LIBS=ON.

The issue is that not all users are including GenericDomTreeConstruction.h,
causing undefined references when ld64 managed to hide the
linkonce_odr symbols.
