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

README 

This directory contains code for binding the test262 test suite
into the v8 test harness. The tests are checked out as a dependency from

  https://chromium.googlesource.com/external/github.com/tc39/test262

at a revision specified in the DEPS file as 'data' in this directory. They are
fetched with 'gclient sync'. To update to a newer version, please change the
DEPS file.

Using a newer version, e.g. 'deadbeef' may be possible but the tests are only
known to pass (and indeed run) with the DEPS revision. Example:

  cd data
  git fetch
  git checkout deadbeef

If you do update to a newer revision you may have to change the test
harness adapter code since it uses internal functionality from the
harness that comes bundled with the tests.  You will most likely also
have to update the test expectation file.
