* tree-vectorizer.c (get_vectype_for_scalar_type): Added debug prinouts.
        Added check that vectype is VECTOR_MODE_P, instead of check for BLKmode.
        (vect_analyze_operations): Make sure the vectorization factor > 1. Add
        gcc_assert under ENABLE_CHECKING.
        (vectorizable_operation): Remove check for VECTOR_MODE_P (moved to
        get_vectype_for_scalar_type).

        (vect_get_vec_def_for_operand): Remove redundant variables.
        (vect_transform_loop): Likewise.
