Concept  patch to show where stuff can be added (finding the cases only)

Here's a raw concept patch which shows (via fprintf) where the work could
be done.  The idea is to look at the statement (and nothing else) and
then create a finalization block around it if there is something to
finalize. When creating the temporary with gfc_create_var, it probably would
make sense to add it to the symbols of the block as well and add it to
the routines to be finalized.

How does that sound?
