expr.c (store_field): Remove warning.
* expr.c (store_field): Remove warning.
(expand_expr, case COMPONENT_REF, case VIEW_CONVERT_EXPR): Likewise.
(highest_pow2_factor, case MIN_EXPR, case MAX_EXPR): Add cases.
(highest_pow2_factor, case *_DIV_EXPR): Only can do something if
divisor constant power of 2.
(highest_pow2_factor, case COMPOUND_EXPR): Look at operand 1.
