[PUSHED] Use range_query object in array bounds class.

[Aldy Hernandez via Gcc-patches]

Now that all dependencies of array_bounds_checker take a range_query, we
can sever the relationship with vr_values.  Changing this will allow us
to use the array_bounds_checker with VRP, evrp, or the ranger.

Tested on x86-64 Linux.

Pushed.

gcc/ChangeLog:

        * gimple-array-bounds.h (class array_bounds_checker): Change
        ranges type to range_query.
