tree-optimization/114027 - conditional reduction chain
When we classify a conditional reduction chain as CONST_COND_REDUCTION
we fail to verify all involved conditionals have the same constant.
That's a quite unlikely situation so the following simply disables
such classification when there's more than one reduction statement.
PR tree-optimization/114027
* tree-vect-loop.cc (vecctorizable_reduction): Use optimized
condition reduction classification only for single-element
chains.
* gcc.dg/vect/pr114027.c: New testcase.
