combine: Use correct mode in new comparison (PR86902)

This code in try_combine uses the wrong mode.  This fails (with RTL
checking) in trunk, but not in any released branches.

PR rtl-optimization/86902
* combine.c (try_combine): When changing the CC mode used, don't change
an unrelated mode in other_insn to that new CC mode.
