Log:
        * tree-vectorizer.c (vect_is_simple_use): Remove multitypes check.
        Moved to vectorizable_* functions.
        * tree-vect-transform.c (vectorizable_reduction): Call
        nested_in_vect_loop_p. Check for multitypes in the inner-loop.
        (vectorizable_call): Likewise.
        (vectorizable_conversion): Likewise.
        (vectorizable_operation): Likewise.
        (vectorizable_type_promotion): Likewise.
        (vectorizable_type_demotion): Likewise.
        (vectorizable_store): Likewise.
        (vectorizable_live_operation): Likewise.

        * tree-vectorizer.c (supportable_widening_operation): Also check if
        used by an outer-loop reduction.
        (vect_is_simple_reduction): Takes a loop_vec_info as argument instead
        of struct loop. Call nested_in_vect_loop_p and don't require
        flag_unsafe_math_optimizations if it returns true.
        * tree-vectorizer.h (vect_is_simple_reduction): Takes a loop_vec_info
        as argument instead of struct loop.
        * tree-vect-analyze.c (vect_analyze_scalar_cycles_1): New function.
        Same code as what used to be vect_analyze_scalar_cycles, only with
        additional argument loop, and loop_info passed to
        vect_is_simple_reduction instead of loop.
        (vect_analyze_scalar_cycles): Codee factored out into
        vect_analyze_scalar_cycles_1. Call it for each relevant loop-nest.
        Updated documentation.
        (vect_mark_stmts_to_be_vectorized): 'relevant' doen't change to
        vect_used_by_reduction in case it is vect_used_in_outer*.
        (vect_analyze_loop_1): Don't call vect_analyze_scalar_cycles.
        * tree-vect-patterns.c (vect_recog_dot_prod_pattern): Check if there
        are uses in the loop.
        * tree-vect-transform.c (vectorizable_reduction): pass loop_info to
        vect_is_simple_reduction instead of loop.

        * tree-vect-analyze.c (process_use): Remove printouts.
        * tree-vect-transform.c (get_initial_def_for_induction): Fix
        indentation.

        * tree-vectorizer.h (nested_in_vect_loop_p): New function.
        * tree-vect-transform.c (vect_init_vector): Call nested_in_vect_loop_p.
        (get_initial_def_for_reduction): Likewise.
        (vect_create_epilog_for_reduction): Likewise.
