* Code: Call super method.
* For: invoke-super, invoke-super/range
* Description: invoke-super is used to invoke the closest superclass's virtual
* method (as opposed to the one with the same method_id in the
* calling class).
* 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)
