commit ddf2a4e4ae9966ceaaf7854226b8fcd007bfe953
Author: Shubhie Panicker <panicker@chromium.org>
Date: Tue Mar 06 00:09:06 2018

Attempt #2: Expose wasDiscarded after tab discard.

This is needed for Lifecycle API, see:
https://github.com/WICG/web-lifecycle
WasDiscarded is set on RequestNavigationParams on browser side and
passed into to WebURLRequest on renderer side. And later
set on the Document in DocumentLoader::CommitNavigation.

commit 194f1d61ffa4b7ff92d93e762deea582a65fa52c

Set RenderFrameHostImpl::was_discarded_ only for successful commits.

This is a quick followup to r540997 to move initialization of
RenderFrameHostImpl's discarded state a bit later in the commit
process, once we know that the commit will be successful.  This will
prevent updating wasDiscarded if the commit fails, for example due to
failing ValidateDidCommitParams or a couple of other cases in
RenderFrameHostImpl::DidCommitProvisionalLoad().
