On Intel processors it seems to be generally beneficial to use pushes
instead of explicit stack massaging to allocate the function callback
arguments on the stack for the API callback.

This yields a 5% improvement on the API callback performance, and
recovers an earlier regression (which was probably due to changing this
code to use movs instead of pushes).
