Objective-C method unintended override checking is one such case where properly checking unintended overrides requires us to essentially look at the whole module, because one translation unit may declare something that produces an Objective-C method "setFoo:" in a superclass while another translation unit declares something with a distinct name that produces an Objective-C method "setFoo:". So, when we don't have a primary file (e.g., when we're doing the merge-module step), delay such checks until after all the source files for the module have been type-checked. When there is a primary file, we perform the checking that we can based on type checking that primary file (and whatever got touched along the way), so we get a subset of the proper diagnostics.
