Fix PR 111331: wrong code for `a > 28 ? MIN<a, 28> : 29`

The problem here is after r6-7425-ga9fee7cdc3c62d0e51730,
the comparison to see if the transformation could be done was using the
wrong value. Instead of see if the inner was LE (for MIN and GE for MAX)
the outer value, it was comparing the inner to the value used in the comparison
which was wrong.

Committed to GCC 13 branch after bootstrapped and tested on x86_64-linux-gnu.
