The down side of constructing a JavaMethodHandle is that if the
additional arguments to the test are different we'd end up
constructing new every time. Obviously avoiding arg boxing is key to
performance, so call paths will need to support a large number of
unboxed arguments to allow passing call protocols along cleanly.

I'll play around with things a bit and see if there's anything
specific to the call site that could be generated once, avoiding the
extra arguments...
