Becca Royal-Gordon ba1ec90419 Generate IR for @_objcImpls ...

This commit begins to generate correct metadata for @_objcImplementation extensions:

• Swift-specific metadata and symbols are not generated.
• For main-class @_objcImpls, we visit the class to emit metadata, but visit the extension’s members.
• Includes both IR tests and executable tests, including coverage of same-module @objc subclasses, different-module @objc subclasses, and clang subclasses.

The test cases do not yet cover stored properties.
