> >
> > - Introduce new operator variants for signed right-shifts with the
> >   additional information that they always shift out zeros.
> > - Use these new operators for Smi untagging.
> > - Merge left-shifts with a preceding Smi-untagging shift.
> > - Optimize comparisons of Smi-untagging shifts to operate on the
> >   unshifted word.
> > - Optimize 64bit comparisons of values expanded from 32bit to use
> >   a 32bit comparison instead.
> > - Change CodeStubAssembler::UntagSmi to first sign-extend and then
> >   right-shift to enable better address computations for Smi indices.
