Always check the return value of fold_range.
The fold_range routine in range-ops returns FALSE if the operation
fails. There are a few places which assume the operation was
successful. Fix those.
* gimple-range-fold.cc (range_of_range_op): Set result to
VARYING if the call to fold_range fails.
* tree-data-ref.cc (compute_distributive_range): Ditto.
* tree-vrp.cc (range_fold_binary_expr): Ditto.
(range_fold_unary_expr): Ditto.
* value-query.cc (range_query::get_tree_range): Ditto.
