Revert of Collect information about failing histogram factory calls. (patchset #6 id:180001 of https://codereview.chromium.org/1719363002/ )

Reason for revert:
Build is no longer exhibiting crashes as before.  It's as though the debug code is preventing whatever error is causing the crashes, or at least those caused by the StatisticsRecorder finding the wrong Histogram.

More to follow...

Original issue's description:
> Collect information about failing histogram factory calls.
>
> Some tests need to be disabled because they create the same histogram with different parameters, a condition which does not always crash in the calling code but does with this CL.
>
> This CL will be reverted once the necessary information has been collected, including re-enabling of any tests.
>
> SHERIFFS: If a test breaks in the waterfall, you can either revert this CL or disable the test.  I'll re-enable it when reverting this after the necessary data has been collected.
