X87: [strong] Check arity of functions

port 3226e980 (28346).

original commit message:

    [strong] Check arity of functions

    In strong mode it is an error to call a function with too few
    arguments.

    This is enforced inside the ArgumentsAdaptorTrampoline.

    This does not yet handle rest parameter
