ifcvt.c (noce_process_if_block): Correctly detect X modified with INSN_B before COND_EARLIEST.

        * ifcvt.c (noce_process_if_block): Correctly detect X modified
        with INSN_B before COND_EARLIEST.  Don't check A and B for
        modification in condition range.  Reorder INSN_B for A==B properly.
        (if_convert): Iterate until no matches for a block.

* gcc.c-torture/execute/20020916-1.c: New.
