Original change's description:
> [array] Implement Array.p.sort in Torque
>
> This CL implements a generic baseline version and 3 fastpaths, for
> various elements kinds, of Array.p.sort in Torque. Details can be found
> in the Design Doc: https://goo.gl/Ge321G.
>
> Performance impact on micro benchmarks depends on the element kind
> and whether the user provides a comparison function.
> For HoleySmi/HoleyElement we have a speedup between 1.5-1.8 across
> the board. For Dictionary we are slower in all micro benchmarks (0.7).
> For PackedSmi it depends on the call site and whether or not a
> comparison function is used.
