        * tree-vectorizer.h (VECT_SCALAR_BOOLEAN_TYPE_P): Define.
        * tree-vect-stmts.c (vect_get_vec_def_for_operand,
        vectorizable_mask_load_store, vectorizable_operation,
        vect_is_simple_cond, get_same_sized_vectype): Use it instead
        of comparing TREE_CODE of a type against BOOLEAN_TYPE.
        * tree-vect-patterns.c (check_bool_pattern, search_type_for_mask_1,
        vect_recog_bool_pattern, vect_recog_mask_conversion_pattern): Likewise.
        * tree-vect-slp.c (vect_get_constant_vectors): Likewise.
        * tree-vect-loop.c (vect_determine_vectorization_factor): Likewise.
        Remove redundant gimple_code (stmt) == GIMPLE_ASSIGN test after
        is_gimple_assign (stmt).  Replace another such test with
        is_gimple_assign (stmt).
testsuite/
        * gcc.c-torture/compile/pr79284.c: New test.
