Consider replacing all occurrences of IsHighResNowFastAndReliable with
IsHighResolution.  IIRC, this is only used in a few files so it shouldn't be a
huge addition to this CL.

Done.

You should also remove references to HighResNow in comments.  Suggest you `git
grep HighResNow` to identify all LOC.  Hopefully, not too many extra files need
to be touched.
