Bug 25202: Improve performance of repeated callbacks into the VM

Reviewed by Cameron Zwarich

Add the concept of a CachedCall to native code for use in Array
prototype and similar functions where a single callback function
is called repeatedly with the same number of arguments.

Used Array.prototype.filter as the test function and got a 50% win
over a naive non-caching specialised version. This makes the native
implementation of Array.prototype.filter faster than the JS one once
more.
