3e2712e018 Lots of small optimizations, and one that is measurable (speeds up celtickane-array signficantly).

4c1a5810b9 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.

d2a8454d2f This change removes the %AddProperty native JavaScript function from V8.
All uses of %AddProperty are replaced by %SetProperty.  A few uses of
IgnoreAttributesAndSetLocalProperty are added, and the runtime version
of it adds a PropertyAttributes argument.  Only the JSObject class
in objects.cc now uses AddProperty, and it can become private.

9da356eea6 Make sure that the name accessor on functions return the expected
names.

- Set the correct name of library functions.
- Set the name of C++ callback functions.
- Clean up a couple of out-dated comments related to literal creation.
