* Code: Call at method. Provides an "isrange" variable and
* a "routine" variable to specify this is the "range" version of
* invoke_interface that allows up to 255 arguments.
* For: invoke-interface, invoke-interface-range
* Description: invoke-interface is used to invoke an interface method; on an
* object whose concrete class isn't known, using a method_id that
* refers to an interface.
* Format: B|A|op CCCC G|F|E|D (35c)
* AA|op BBBB CCCC (3rc)
* Syntax: [B=5] op {vD, vE, vF, vG, vA}, meth@CCCC (35c)
* [B=5] op {vD, vE, vF, vG, vA}, type@CCCC (35c)
* [B=4] op {vD, vE, vF, vG}, kind@CCCC (35c)
* [B=3] op {vD, vE, vF}, kind@CCCC (35c)
* [B=2] op {vD, vE}, kind@CCCC (35c)
* [B=1] op {vD}, kind@CCCC (35c)
* [B=0] op {}, kind@CCCC (35c)
* op {vCCCC .. vNNNN}, meth@BBBB (3rc) (where NNNN = CCCC+AA-1, that
* op {vCCCC .. vNNNN}, type@BBBB (3rc) is A determines the count 0..255,
* and C determines the first register)
