ExternalCallbackScope is used to let CPU profiler know which API callback is being executed. Whenever such callback is called we should create VMState<ETERNAL> and ExternalCallbackScope. This patch fixes several places where VMState<ETERNAL> went without ExternalCallbackScope. BUG=244580 R=dcarney@chromium.org, svenpanne@chromium.org Review URL: https://codereview.chromium.org/17059005 git-svn-id: http://v8.googlecode.com/svn/branches/bleeding_edge@15249 ce2b1a6d-e550-0410-aec6-3dcde31c8c00
