param.h (MIN_VECT_LOOP_BOUND): New.
* param.h (MIN_VECT_LOOP_BOUND): New.
* params.def (MIN_VECT_LOOP_BOUND): New.
* tree-vectorizer.c (slpeel_tree_peel_loop_to_edge): Takes another
argument - minimum threshold for number of iterations.
* tree-vectorizer.h (slpeel_tree_peel_loop_to_edge): Add another
argument to declaration.
* tree-vect-analyze.c (vect_analyze_operations): Check value of
MIN_VECT_LOOP_BOUND.
* tree-vect-transform.c (vect_do_peeling_for_loop_bound): Call
slpeel_tree_peel_loop_to_edge with additional argument.
(vect_do_peeling_for_alignment): Likewise.
* doc/invoke.texi (min-vect-loop-bound): Document new param option.
