Modules occupy a weird space in the AST now: they can be treated like types (Swift.Int), which is captured by ModuleType. They can be treated like values for disambiguation (Swift.print), which is captured by ModuleExpr. And we jump through hoops in various places to store "either a module or a decl". Start cleaning this up by transforming Module into ModuleDecl, a TypeDecl that's implicitly created to describe a module. Subsequent changes will start folding away the special cases (ModuleExpr -> DeclRefExpr, name lookup results stop having a separate Module case, etc.). Note that the Module -> ModuleDecl typedef is there to limit the changes needed. Much of this patch is actually dealing with the fact that Module used to have Ctx and Name public members that now need to be accessed via getASTContext() and getName(), respectively.
