Don't store the live range of the freed variable for FREE_ON_RETURN frees, instead look it up at runtime. As this is an extremely unlikely codepath (in particular, it requires a loop variable with a throwing destructor), saving the runtime lookup of the live range is not worth the extra complexity this adds everywhere else.
