re PR rtl-optimization/13400 (Compiled code crashes storing to read-only location)

PR middle-end/13400
* ifcvt.c (noce_process_if_block): Disable unconditional write
optimizations if we could introduce a store to trapping memory
that wasn't present previously.

* gcc.c-torture/execute/20031215-1.c: New test case.
