Can you also make sure that the normal histograms are logged correctly?

Done.

Can you add a check to make sure that nothing was logged for your new histogram?
Like 
histograms.ExpectBucketCount("Autofill.FormEvents.CreditCard.OnNonsecurePage",
AutofillMetrics::FORM_EVENT_NO_SUGGESTION_SUBMITTED_ONCE, 0);

[estark, 2017/02/04 02:16:13]

Done.
