This could be moved to an android location with the ifdef.

Why have AutofillHandlerProxy be a wrapper for Autofill Provider? As opposed to
having AutofillProvider directly implement AutofillHandler?

[michaelbai, 2017/05/24 20:43:23]

It because that a WebContents has one AutofillProvider, but AutofillHandler
relates to frame.

As we discussed, we will not use ifdef.
