Intermediate patch

I've tried to experiment with something like this... Intermediate patch.

There is makeExemptFromThreadCheck() function that stores a per-instance flag
which I was hoping to use to have some sort of 'dynamic opt-out'. To make it
possible to 'temporarily exclude' an instance of RefCounted from the
requirement to be refcounted on the same thread - and then use it for things
like String, relaxing the check in certain portions of code and still asserting
in others. But IconDatabase quickly discouraged me from this... It is very
hard, looking at code, to know where to enable/disable the check. Usage on
different threads can happen in way distant codepaths.
