Not really a new compiler. OdinMonkey parses the asm.js type system, but then just passes the information it learned into IonMonkey, the existing SSA-optimizing JIT.

OdinMonkey uses the existing IonMonkey compiler to do the actual optimization and code generation work. This blog post has more information [0]; see especially the comments section where the author responds to some questions and discusses the relationship between OdinMonkey and regular JS compilation.
