Subject: Make deopt testing compatible with runtime optimization status queries.
X-Git-Tag: upstream/4.7.83~13366
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=5e343cd2a9e112bbbc221d3c91ec86e275608d98;p=platform%2Fupstream%2Fv8.git

Make deopt testing compatible with runtime optimization status queries.

When deopt testing is activated, a new status code will be returned by optimization status queries (status=maybe deopted).

This will make those tests work that test for 'not status=no', when performing deopt testing.
