    Use the current cache when creating inferred ranges.
    
    Infer range processing was adjusted to allow a query to be specified,
    but during VRP folding, ranger was not providing a query.  This results
    in contextual ranges being missed.   Pass the cache in as the query
    which provide a read-only query of the current state.
    
            * gimple-range-cache.cc (ranger_cache::apply_inferred_ranges): Pass
            'this' as the range-query to the inferred range constructor.
