Add stats for last step inlining of invokes

Add kInlinedLastInvoke(VirtualOrInterface) which counts the amount of invokes we inlined on the parent-most method. This is useful to know since it is the invoke that matters the most. The other inlinings are about recursive inlinings but those will not get into the graph if the last invoke fails to be inlined.
