John Cuthbertson 6110c052aa 6943926: G1: Integer overflow during heap region verification 
The expression that calculates the live bytes for a heap region can overflow for a suitably large humongous region/object. Cache the object size in a suitably sized local variable so that the expression is converted to a wider type.
