How many tests do we have that need special options?  If the number
is small we can probably do what we want by using a special driver
for those tests.

If the number is large or expected to grow, then we'll want to do
something along the lines of old-deja or gcc.dg

6 one way, half a dozen the other.  I think we just add {-O2 -g} to
the list of TORTURE_OPTIONS.

Well, we probabl should have updated f-torture for the -g stuff when
we updated c-torture.  Got to get everyone in the habit of changing
them together :-)
