Most of the speed benefits of x264 come from
1) Handwritten ASM code
2) Threading

Both of these are going to cause issues to any attempt to port it to
JS without disabling both of the features.
As such, any JS port made out of x264 will be seriously speed crippled
to where there's not particularly any benefit...
