Keyed store stub sits high in sorting profiles.
Swapping allows to save us additional type checks as we could both read and
write elmenets (on fast path) without them.

Implement Array::concat function in C++.

The performance of Array::concat is critical of jQuery benchmark from
http://www.dromaeo.com . Our current implementation in JavaScript is very
generic and is several times slower than JSC and SpiderMonkey.
Re-implement Array::concat in C++ to take advantage of underlying implementation
details. This cuts dom-travesal-jquery execution time by half.
We may want to move Array specific implementation into a separate source file,
say jsarray.cc.
