    Do not invoke a different range query from within fold_stmt.

    fold_using_range works on a specified range_query object.  IF this
    object is not the current_range_query (cfun) object, do not invoke
    the general gimple fold routines as they may call into the current
    query.

            * gimple-range-fold.cc (fold_using_range::fold_stmt): Check if the
            range_query matches the current one before invoking fold.
