Remove builderror.log

It shouldn't have been versioned in the first place, remove it.
Update to V8 v3.22 API.

The V8 API has changed a great deal.  Update strong-cpu-profiler
accordingly.

Notable changes to the strong-cpu-profiler include the removal of the
following functions and properties:

  * CpuProfile#getBottomUpRoot()
  * CpuProfileNode#selfSamplesCount
  * CpuProfileNode#selfTime
  * CpuProfileNode#totalSamplesCount
  * CpuProfileNode#totalTime

Their corresponding V8 methods have disappeared with no real
replacement.
