-enable-source-import doesn't play nice with debug info, and we want to be
able to run all tests with -g added. The last few tests that require
-enable-source-import could be built with --no-debug-info, or however we
end up spelling that.

...unless they are in a private class.
Consider this scenario:
class Base {
func foo() -> Base { ... }
}
class Sub : Base {
private override func foo() -> Sub { ... }
}
class Grandchild : Sub {
override func foo() -> Base { ... }
}
Because Grandchild can't see Sub, its override of foo() looks perfectly
reasonable...but now Sub's expectations for foo() have been broken.

Emit ObjC stubs and categories for methods defined in extensions of ObjC-compatible classes. This makes extensions of ObjC classes available to ObjC in statically compiled code. For immediate-mode code we'll still need to dynamically register extension methods using the ObjC runtime.
