ThreadedFFIPlugin
Provide a ffiCalloutTo:SpecOnStack:in: for ARMv8 that passes all 8 integer
register parameters.
Provide an overview of the implementation architecture in the class comment
of ThreadedFFIPlugin.

Please LMK of any confusing or erroneous info in the class comment.  Feel
free to extend the information, e.g. with pointers to suitable ABI
documentation that I realize I could have provided.
