* tree-vectorizer.c (new_loop_vec_info): Initialize
LOOP_VINFO_COST_MODEL_MIN_ITERS.
* tree-vectorizer.h (_loop_vec_info): Added new filed
min_profitable_iters.
(LOOP_VINFO_COST_MODEL_MIN_ITERS): New access macro to above new field.
(TARG_SCALAR_TO_VEC_COST): Define cost of scalar to vector operation.
* tree-vect-analyze.c (vect_analyze_operations): Set
LOOP_VINFO_COST_MODEL_MIN_ITERS.
* tree-vect-transform.c (vect_estimate_min_profitable_iters): Use
VEC_length to determine if there are any LOOP_VINFO_MAY_MISALIGN_STMTS.
Fix calculation of peel_iters_prologue. Move consideration of epilogue
and prologue cost to after they are computed.
(vect_model_induction_cost): Use TARG_SCALAR_TO_VEC_COST instead of
TARG_VEC_STMT_COST.
(vect_model_simple_cost): Takes additional argument dt. Consider cost
of creating vectors from scalars according to dt.
(vect_model_store_cost): Likewise.
(vectorizable_call): Use dt array instead of scalar dt. Call
vect_model_simple_cost with additional argument dt.
(vectorizable_assignment): Likewise.
(vectorizable_operation): Likewise.
(vectorizable_type_demotion): Likewise.
(vectorizable_type_promotion): Likewise.
(vectorizable_store): Use dt array instead of scalar dt. Call
vect_model_store_cost with additional argument dt.
(vect_do_peeling_for_loop_bound): Don't call
vect_estimate_min_profitable_iters. Instead, lookup
LOOP_VINFO_COST_MODEL_MIN_ITERS. Don't always print
"may not be profitable".
