* tree-vectorizer.c (vect_is_simple_use): Support induction.
(vect_is_simple_reduction): Support reduction with induction as
one of the operands.
(vect_is_simple_iv_evolution): Fix formatting.
* tree-vect-analyze.c (vect_mark_stmts_to_be_vectorized): Fix
formatting. Don't mark induction phis for vectorization.
(vect_analyze_scalar_cycles): Analyze all inductions, then reductions.
* tree-vect-transform.c (get_initial_def_for_induction): New function.
(vect_get_vec_def_for_operand): Support induction.
(vect_get_vec_def_for_stmt_copy): Fix formatting and add check for
induction case.
(vectorizable_reduction): Support reduction with induction as one of
the operands.
(vectorizable_type_demotion): Use def-type of stmt argument rather
than dummy def-type.
* tree-ssa-loop.c (gate_scev_const_prop): Return the value of
flag_tree_scev_cprop.
* common.opt (tree-scev-cprop): New flag.
* tree-vect-transform.c (vect_create_destination_var): Use 'kind' in
call to vect_get_new_vect_var.
