`tryPushBack` overloads

== Synopses

Declared in `<bdlcc_deque.h>`

If the container is not full (see {`High‐Water Mark` Feature}), append the specified move‐insertable `item` to the back of the container, otherwise leave the container unchanged. If the container is modified, `item` is left in a valid but unspecified state, otherwise `item` is unchanged. Return 0 if the container was updated and a non‐zero value otherwise.

Push as many of the items in the specified range `[begin .. end)]` as there is space available for (see {`High‐Water Mark` Feature}) to the back of the container, stopping if the container high‐water mark is reached. Return the number of items pushed. Note that the items in the range are treated as `const` objects, copied without being modified.
