Check for undefined before not returning a constant value
Don't return UNDEFINED for a range in an unreachable block if the global
value evaluates to a constant. Return that constant instead.
PR tree-optimization/97515
* value-query.cc (range_query::value_of_expr): If the result is
UNDEFINED, check to see if the global value is a constant.
(range_query::value_on_edge): Ditto.
