Previously, if a declaration belonged to a module with an `export_as` attribute, Swift always used the exported module name in the public module interface and the real module name in the private module interface. However, this is only a rough approximation of the behavior we really want, which is to use the real name in module interfaces that might be imported by dependencies of the exported name. Change this logic so that public interfaces always use the exported name, and private interfaces use the exported name *only* if a module with that name has been loaded. This should make it so that if you’re building the `export_as` module or anything that imports it, you use the exported name; otherwise you use the real name. Fixes rdar://167874630.
