Reverted r209489 for reason: Likely caused large regressions on JetStream, Sunspider and Speedometer Committed r209544: <http://trac.webkit.org/changeset/209544>

Reverted r209544 for reason: Looks like r209489 did not cause the performance regression after all Committed r209773: <http://trac.webkit.org/changeset/209773>
