Subject: Unbreak bleeding_edge by getting the Parser to work with a CompilationInfo instead... 
X-Git-Tag: upstream/4.7.83~16492
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=6fef6e451c6cf14db72ae106ba116cee08cc675e;p=platform%2Fupstream%2Fv8.git

Unbreak bleeding_edge by getting the Parser to work with a CompilationInfo instead of a Handle<Script> and a Zone.  This should have been fixed in the initial patch itself but escaped my attention.

TEST=
