New collection hash functions are too slow

Description

As reported ( https://groups.google.com/d/msg/clojure-dev/t6LAmVe-RLM/ekLTKxYfU5UJ ) by Mark Engelberg, the new collection hashing functions are slower than invoking the Murmur3 functions directly. See the attached zip for performance tests.

Approach: Made mix-collection-hash, hash-ordered-coll, and hash-unordered-coll use primitive type hints to avoid the bulk of the time.
