    Don't calculate new values when using the private context callback.

    When using rangers private callback mechanism to provide context
    to fold_stmt calls, we are only suppose to be using the cache in read
    only mode, never calculate new values.

            * gimple-range.cc (gimple_ranger::range_of_expr): Request the cache
            entry with "calulate new values" set to false.
