This completes the FileUnit refactoring. A module consists of multiple FileUnits, which provide decls from various file-like sources. I say "file-like" because the Builtin module is implemented with a single BuiltinUnit, and imported Clang modules are just a single FileUnit source within a module. Most modules, therefore, contain a single file unit; only the main module will contain multiple source files (and eventually partial AST files). The term "translation unit" has been scrubbed from the project. To refer to the context of declarations outside of any other declarations, use "top-level" or "module scope". To refer to a .swift file or its DeclContext, use "source file". To refer to a single unit of compilation, use "module", since the model is that an entire module will be compiled with a single driver call. (It will still be possible to compile a single source file through the direct-to-frontend interface, but only in the context of the whole module.) Swift SVN r10837
