re PR tree-optimization/43842 (ice in vect_create_epilog_for_reduction)
PR tree-optimization/43842
* tree-vect-loop.c (vect_create_epilog_for_reduction): Handle
loop unrolling in update of exit phis. Fix comment.
* tree-vect-slp.c (vect_analyze_slp): Check that there are at
least two reduction statements in the loop before starting SLP
analysis.
