I agree about your concerns on code maintainability. Please note that the
patch was uploaded just for feedbacks/questions/concerns (like this. :)). I
believe that this patch can be further re-factored (especially the code in
WeCore/GNUmakefile.am and WebCore/GNUmakefile.list.am files) so that it
eases the code maintenance (which I am willing to do anyways). We could aim
to push this patch with at-most isolation as possible.

Below are the result based on a quick performance benchmarking, with 91387
of WebKit and 8745 revision of V8

Benchmarking Suite : V8 benchmark suite by Google
URL : http://v8.googlecode.com/svn/data/benchmarks/v6/run.html
Host machine: x86-64
Score with SFX: 3454
Score with V8: 8366

Of-course,  judgment on performance benefit cannot be based only on V8
bench-marking suite. I will provide the results with Sunspider and Dromaeo
suite soon.
