re PR middle-end/58941 (value modification on zero-length array optimized away)

2013-11-05  Richard Biener  <rguenther@suse.de>

PR middle-end/58941
* tree-dfa.c (get_ref_base_and_extent): Merge common code
in MEM_REF and TARGET_MEM_REF handling.  Make sure to
process trailing array detection before diving into the
view-converted object (and possibly apply some extra offset).

* gcc.dg/torture/pr58941.c: New testcase.
