Description

Currently the unchecked-* functions and macros simply alias the primitive js operators. It would be nice if the unchecked-*-int family of functions and macros implemented C/Java-like signed int operations with silent overflows (just like in Clojure) using asm.js coersion idioms. This should also allow us to share such code between clojure and clojurescript without worrying about their different numerics.

A use case is that porting hash algorithms from java to clojurescript is trickier and more verbose than it needs to be.

This sounds interesting, would like to see more thoughts on approach, benchmarks etc.
