I managed to convince myself that it's not higher-level code's
responsibility to invoke the execute hooks; the likelihood of bugs of
omission seems just too large.  But maybe I'm wrong.

There's a small number of InvokeFunctionExecuteHook calls in the
executor, but I really doubt that it exhaustively covers everyplace
where catalogued functions are called in the executor.

CC'ing KaiGai and Stephen Frost; they may want to chip in here.
