As per #65930, the Clang importer's Clang instance may be configured with a different (higher) OS version than the compilation target itself in order to be able to load pre-compiled Clang modules that are aligned with the broader SDK, and match the SDK deployment target against which Swift modules are also built. Code-generation, however, must use the actual compilation target triple. This matches how Swift itself loads Swift module dependencies as well: dependency '.swiftinterface' files are type-checked against the availability epoch and code-generated against the actual compilation triple.
