`max_load_factor` overloads

== Synopses

Declared in `<bslstl_unorderedmap.h>`

Return the maximum load factor allowed for this unordered map. Note that if an insert operation would cause the load factor to exceed the `max_load_factor`, that same insert operation will increase the number of buckets and rehash the elements of the container into those buckets (see `rehash`).

Set the maximum load factor of this unordered map to the specified `newMaxLoadFactor`. If `newMaxLoadFactor < loadFactor()`, this operator will cause an immediate rehash (in violation of the C++11 standard); otherwise, it has a constant‐time cost. The behavior is undefined unless `0 < newMaxLoadFactor`.
