...unless the functions are declared [transparent], or if we're in an immediate mode (in which case we won't get a separate chance to link against the imported TUs). This is an optimization that will matter more when we start dealing with Xcode projects with many cross-file dependencies, especially if we have some kind of implicit import of the other source files in the project. In the future, we may want to parse more function bodies for the purpose of inlining, not just the transparent ones, but we weren't taking advantage of that now, so it's not a regression. (We're still not taking advantage of it even for [transparent] functions.) Swift SVN r7698
