Deduce the template parameters KEY and VALUE from the value_type of the iterators supplied to the constructor of unordered_multimap. Deduce the template parameter ALLOCATOR from the other parameter passed to the constructor of unordered_multimap. This deduction guide does not participate unless the supplied allocator meets the requirements of a standard allocator.
