Improve performance of dynamic invocation of dynamic navs

[nathanmarz]

Doing something like (reduce multi-path STOP paths) could be significantly faster, as it's currently paying the cost of an apply in both late-bound-operation and wrap-dynamic-nav. late-bound-operation also does sequence creation/traversal while checking whether args are dynamic or not. With unrolling and more work in the late-bound-operation macro, all of this overhead can be eliminated.

Should also look into optimizing dynamic-param? by using a marker interface that each dynamic type implements. Then dynamic-param? just does an instance? check on that type rather than checking for each specific type.
