gcc46-pr45596.patch

Updated patch.  This one should handle the case where pointer assigment just
points into some other var's array section and similar (ie. when there is a
possible overlap with some other var, but not necessarily the same
rank/start/bounds) and has some limited interprocedural points-to handling.
tonto.f90 isn't still handled, because for the pointer ALLOCATE it compares the
pointer symbol on which the ALLOCATE is called, and with create_ doing the
ALLOCATE on self that's the same symbol in both cases (although GFC_PT_CALL in
both cases is through different variables).
