Call through zend_call_function() is more expensive than through TRAMPOLINE.
Why it's not possible to reuse the same trampoline?
May be it makes sense to move trampoline function into zend_closure and free it together with closure object...

Dmitry - I don't really understand trampolines. So long as this PR is acceptable and the tests all pass, is it okay for you to do any performance improvements you think are good, after this PR is accepted and closed?

Yeah. Commit this. I'll take a look, if it's possible to optimise this using trampolines later.
