Perform splatarray false peephole optimization for invokesuper in addition to send

This optimizes cases such as:

  super(arg, *ary)
  super(arg, *ary, &block)
  super(*ary, **kw)
  super(*ary, kw: 1)
  super(*ary, kw: 1, &block)

The super(*ary, **kw, &block) case does not use the splatarray false
optimization.  This is also true of the send case, since the
introduction of the splatkw VM instruction.  That will be fixed in
a later commit.
