More performance explorations

[Charles Oliver Nutter]

I did make another small discovery: the + calls never inline
completely. They eventually are a virtual invocation of
RubyFixnum.op_plus, and in both old and new builds they're calls in
the asm.

This makes me wonder if Rémi was right about userland virtual
invocations never inlining at the end of a method handle chain. Can
that truly be the case? If so, it would mean most of JRuby's core
class methods won't inline...a sad state of affairs :(
