tree-optimization/123221 - ICE with conversion reduction

The following avoids ICEing with a reduction only consisting of
noop-conversions.

PR tree-optimization/123221
* tree-vect-loop.cc (vectorizable_reduction): When we did not
find the non-conversion reduction operation, bail.

* gcc.dg/vect/vect-pr123221.c: New testcase.
