For future reference, this ^^.  You need to update histograms.xml.

You should have also gotten a warning for not having a valid reviewer for
extension_function_histogram_value.h (you're supposed to need a metrics
reviewer).

I've updated histograms.xml to include these in
crrev.com/b2eb97880d384168ae17cfe24b3c874d72428141 so no need to for this patch.
