fold_builtin_alloca_for_var should record stack alignment
change due to
+ /* Declare array. */
+ elem_type = build_nonstandard_integer_type (BITS_PER_UNIT, 1);
+ n_elem = size * 8 / BITS_PER_UNIT;
+ align = MIN (size * 8, BIGGEST_ALIGNMENT);
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
+ array_type = build_array_type_nelts (elem_type, n_elem);
+ var = create_tmp_var (array_type, NULL);
+ DECL_ALIGN (var) = align;
