A few of the changes in https://bugs.webkit.org/show_bug.cgi?id=162660 need more investigation.
Also look into why imported/w3c/web-platform-tests/XMLHttpRequest/send-network-error-sync-events.sub.html changes.
And http/tests/websocket/tests/hybi/handshake-ok-with-http-version-beyond-1_1.html
Also look into http://trac.webkit.org/changeset/207167
And https://bugs.webkit.org/show_bug.cgi?id=163307
I skipped these two tests on the iOS simulator: http/tests/quicklook/secure-document-with-subresources.html accessibility/text-marker/character-offset-visible-position-conversion-hang.html
Unskipped iOS tests in http://trac.webkit.org/changeset/208814
