This will be used after https://codereview.chromium.org/1881773002/.  I'd like
to see if we can get the close reason to be correct in this patch so that we
don't lose functionality that will be needed for combining with
ExtensionMessageBubble.

Done.

[Devlin, 2016/04/12 23:01:05]

optional nit: I'd slightly prefer a switch here so that we can NOTREACHED on
ui::DIALOG_BUTTON_NONE and DCHECK(!delegate_->GetDismissButtonText().empty()) on
ui::DIALOG_BUTTON_CANCEL, and if we ever add something like a
ui::DIALOG_BUTTON_LEARN_MORE or lump close buttons in there or anything, we get
a compile error.

I see what you're saying, but this pattern is pretty standard across dialogs.
