Timur, can you please use fewer wildcards?

In the memcheck suppression files, we tend to use
them very, very infrequently.

With ThreadSanitizer we do the opposite.
Can you please discuss it with Kostya?
He convinced me to use wildcards.

Updated the suppression: deleted bug_21474 suppressions since the issue was
fixed

Dan,
Do I need to do anything else with this changelist?

[dank, 2009-09-23 09:34:12]

It's tempting to say make LoadLog derive from ThreadSafeRefCounted
(if that's the right fix) rather than suppress 22272.
But LGTM.

This is what I wanted to do, but here http://codereview.chromium.org/215011
we've decided to fix multi-threaded usage of LoadLog rather than allow it.
