* tree-vectorizer.h (struct _stmt_vec_info): Add th field as the
threshold of number of iterations below which no vectorization will be
done.
* tree-vect-loop.c (new_loop_vec_info):
Initialize LOOP_VINFO_COST_MODEL_THRESHOLD.
* tree-vect-loop.c (vect_analyze_loop_operations):
Set LOOP_VINFO_COST_MODEL_THRESHOLD.
* tree-vect-loop.c (vect_transform_loop):
Use LOOP_VINFO_COST_MODEL_THRESHOLD.
* tree-vect-loop.c (vect_analyze_loop_2): Check the maximum number
of iterations of the loop and see if we should build the epilogue.
