`insertUnique` overloads

== Synopses

Declared in `<bdlcc_stripedunorderedcontainerimpl.h>`

Insert into this hash map an element having the specified `key` and the specified move‐insertable `value`. If `key` already exists in this hash map, the value attribute of that element is set to `value`. Return 1 if an element is inserted, and 0 if an existing element is updated. The `value` object is left in a valid but unspecified state. If `value` is allocator‐enabled and `allocator() != value.allocator()` this operation may cost as much as a copy. Note that the return value equals the number of elements inserted.
