Details

In CodeGeneratorX86::asmJSAtomicComputeAddress we find this comment:

    // Add in the actual heap pointer explicitly, to avoid opening up
    // the abstraction that is atomicBinopToTypedIntArray at this time.

Now that atomicBinopToTypedIntArray is moving into the various back-ends (bug 1202650) we can optimize this, we may save on both instruction count and register pressure.
