* tree-vrp.c (set_value_range): Check that min and max are not
both overflow infinities.
(set_value_range_to_value): New static function.
(extract_range_from_binary_expr): Call set_value_range_to_value.
(extract_range_from_cond_expr): Likewise.
(extract_range_from_expr): Likewise.
(extract_range_from_unary_expr): Likewise. Don't create a range
which overflows on both sides.
(vrp_meet): Check for a useless range.
(vrp_visit_phi_node): If we see a constant which looks like an
overflow infinity, turn off the TREE_OVERFLOW flag.
