Hmm, right.  Then we could probably just examine the LHS of 'STORE =
STORE' expressions, which should only be those that have CALL_EXPR on
the RHS.

Since there shouldn't be many of those, we could factor out the routines
that gather symbols from memory expressions in the operand scanner.
Yucky, but I don't see too many other options.  It shouldn't impact
compile times too much (this situation shouldn't be too common).
