Side car data: emit side car file from KnownObjCMethods.def.

Extend swift-ide-test with a mode that generates a side car file from
the built-in KnownObjCMethods.def, which gives us an easy way to
source the information we want in the side car. This is a temporary
measure until we have a textual format for side car data and the
ability to translate that into the binary format.
