Patch by Timur Iskhodzhanov <timurrrr@google.com> on 2011-03-30
Reviewed by Alexey Proskuryakov.

By using these annotations we can improve the precision of finding
WebKit errors using dynamic analysis tools like ThreadSanitizer and Valgrind.
These annotations don't affect the compiled binaries unless USE(DYNAMIC_ANNOTATIONS) is "1".

These files don't add new functionality, so don't need extra tests.
