`push_front` overloads

== Synopses

Declared in `<bslstl_deque.h>`

Prepend to the front of this deque the specified move‐insertable `value`. `value` is left in a valid but unspecified state. If an exception is thrown (other than by the move constructor of a non‐copy‐insertable `value_type`), this method has no effect. This method requires that the (template parameter) `VALUE_TYPE` be `move‐insertable` into this deque (see {Requirements on `VALUE_TYPE`}).

Prepend to the front of this deque a copy of the specified `value`. This method offers full guarantee of rollback in case an exception is thrown. This method requires that the (template parameter) `VALUE_TYPE` be `copy‐constructible` (see {Requirements on `VALUE_TYPE`}).
