Deduce the template parameter `KEY` from the `value_type` of the initializer_list supplied to the constructor of `unordered_multiset`. Deduce the template parameters `HASH` and `ALLOCATOR` from the other parameters passed to the constructor. This deduction guide does not participate unless the supplied `HASH` is invocable with a `KEY`, and the supplied allocator meets the requirements of a standard allocator.

Declared in `<bslstl_unorderedmultiset.h>`
