Original change's description:
> [array] Use random middle element to determine pivot during sorting
> 
> This CL adds a "random state" to the Smi Root list and implements a
> basic Linear congruential pseudo random number generator in Torque.
> 
> The RNG is used to determine the pivot element for sorting. This will
> prevent the worst cases for certain data layouts.
> 
> Drive-by-fix: Make sorting of ranges and execution pauses for profviz
> deterministic by adding a secondary sorting criteria.
> 
> Bug: v8:7382
