machenbach@chromium.org 3c9efdeeb4 Migrate more tests from blink repository.
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
