Bob Duff guesses that if you store virtual origins and suppress checks you
do not need to pass bounds around.
It's tricky, since we intend in GNAT to use virtual origins at some point
(it is exactly why we use "fat" pointers for unconstrained types), we have
looked into this issue in some detail.
The trouble is that there are a number of subsidiary language features
that will require the bounds ('Address, 'Access, passing array to a
foreign routine ...)
