Optional nit: I'd name these histograms something like

"Translate.CompactUI.Language.AlwaysTranslate",
"Translate.CompactUI.Language.MoreLanguages",
etc.

(It's also fine to use "Translate.Compact.Infobar" if you think that name is
clearer -- though I'd kind of expect "Compact" to always be associated with
"Infobar", so I'd group it as "Translate.CompactInfobar".)

Thanks for the suggestion Ilya. I have renamed these to
Translate.CompactInfobar.Language.

Seems like this histogram could use an enum associated with it, so that users
don't have to manually look up hashcode values.  Ditto for the other
hashcode-recording histograms.

Thanks. Yes, I was able to reuse the enum CLD3LanguageCode.
