Unusual things in this block: - This is my first attempt to fix a multitest with various errors in it, double_parse_test.dart. Most of them revolve around multitest #01 and the conflict it has with the new multitest #04. BUG= R=rnystrom@google.com Review-Url: https://codereview.chromium.org/2988573002 .
