    Don't process lookups for debug statements in Ranger.

    Although PR 100781 is not an issue in GCC11, its possible that a similar
    situation may arise.  The identical fix cannot be easily introduced.
    With EVRP always running in hybrid mode, there is no need for ranger to
    spawn a lookup for a debug statement in this release.

            * gimple-range.cc (gimple_ranger::range_of_expr): Treat debug
statments
            as contextless queries to avoid additional lookups.=
