This change ensures that when loading some module dependency 'Bar' which has a package-only dependency on 'Foo', only the following clients attempt to resolve/load 'Foo': - Source compilation with package-name equal to that of 'Bar'. - Textual interface compilation of a *'package'* interface with package-name equal to that of 'Bar'. Ensuring that the following kinds of clients do not attempt to resolve/load 'Foo': - Source compilation with package-name different to that of 'Bar' - Textual interface compilation of a public or private interface, regardless of package name. This fixes the behavior where previously compilation of a Swift textual interface dependency 'X' from its public or private interface, with an interface-specified package-name, from a client without a matching package-name, resulted in a lookup of package-only dependencies of modules loaded into 'X'. This behavior is invalid if we are not building from the package textual interface, becuase the module dependency graph is defined by the package name of the source client, not individual module dependency package name. i.e. In-package module dependencies are resolved/loaded only if the parent source compile matches the package name.
