Hmm, it's not nice to write 'blink::' in wtf. It's a layering violation. Maybe
we need to move CompressibleString to wtf, but let's worry about the issue
later.

Sure, I'll move this to wtf soon again.

We found that CompressibleString depends on blink::SharedBuffer, which means we
can't move CompressibleString to wtf easily...
