The stand-alone test driver is changed a bit: - Don't use the errorMessage list. It is used differently in the embedded driver. There it collects parser errors - instead of failure messages. - Remove html links in description texts. Some test descriptions print a web reference. The migrated tests fall into 3 categories: 1. Tests outside fast/js 2. Tests that print FAIL messages (and also expect those) - these tests should be examined later if they make sense at all 3. Tests with html links in the test description R=jkummerow@chromium.org Review URL: https://codereview.chromium.org/20280003 git-svn-id: http://v8.googlecode.com/svn/branches/bleeding_edge@15889 ce2b1a6d-e550-0410-aec6-3dcde31c8c00
