This reverts commit 5a389395.

Reason for revert: Breaks some chromium tests. Not your fault, but it's blocking the roll so we have to fix those first -- then you can reland without changes: https://ci.chromium.org/p/v8/builders/luci.v8.ci/V8%20Linux%20-%20debug/21727

Original change's description:
> [array] Move Array.p.sort to Torque and use TimSort instead of QuickSort
> 
> This CL changes the sorting algorithm used in Array.p.sort from
> QuickSort to TimSort (implemented in Torque).
> 
> Detailed performance results can be found here: https://goo.gl/4E733J
> 
> To save on code space, fast-paths are implemented as sets of
> function pointers instead of specializing generics.
