* tree-vectorizer.h (is_pattern_stmt_p): New.

        * tree-vect-analyze.c (vect_determine_vectorization_factor): Fix
        formatting (tabs instead of spaces). Cleanup and clarify setting
        of STMT_VINFO_VECTYPE. Call is_pattern_stmt_p.
        * tree-vect-transform.c (vect_get_vec_def_for_operand): Fix typo.
        (vectorizable_type_demotion): Check that types are integral.
        (vectorizable_type_promotion): Likewise.
        (vectorizable_store): Fix typo.  Eliminate new-line at end of
        comments.
