These instructions all call out to a C function, passing EC, self, and
some number of arguments. invokebuiltin gets the arguments from the
stack, whereas the _delegate instructions use a subset of the locals.
opt_invokebuiltin_delegate_leave has a fast path for leave, but I'm
not sure we need to do anything special for that here (FWIW YJIT appears
to treat the two delegate instructions the same).
