In theory a V8 could optimize regular JS as fast as asm.js, but in practice OdinMonkey made this code 3x to 10x faster (or more) with a couple months of effort. And to boot it is completely compatible with every JS engine, and the code generated can be cached offline for fast startup (because of the linking part), and the FFI between JS and asm.JS is trivial.
Basically this post is sour grapes. Mozilla came up with a better idea than the so-called geniuses at Google did.
