* tree-vect-loop.c (vect_is_simple_reduction_1): Remove
IL rewrite for MINUS_EXPR reductions, rename back to ...
(vect_is_simple_reduction): ... this, removing the wrapper.
(vect_force_simple_reduction): Adjust.
(vectorizable_reduction): Adjust reduc_index for MINUS_EXPR
reductions and make use if reduc_index in all places. For
the final reduction of MINUS_EXPR use PLUS_EXPR.
* gcc.dg/vect/pr67790.c: New testcase.
