Kotlin: Implement JvmOverloads annotation

Browse Source 
This generates functions that omit parameters with default values, rightmost first, such that Java can achieve a similar experience to Kotlin (which represents calls internally as if the default was supplied explicitly, and/or uses a $default method that supplies the needed arguments).

A complication: combining JvmOverloads with JvmStatic means that both the companion object and the surrounding class get overloads.
