The empty impls don't really make sense, I might just add a comment to note that
they are not defined in !ENABLE(ASSERT) cases and they can only be used inside
ASSERT or DCHECKs.

(I defer the decisions to Kent-san)

I agree with you. Changed to be a comment.

 WTF_EXPORT bool isAtomicallyInitializedStaticMutexLockHeld();
 WTF_EXPORT bool isBeforeThreadCreated();
 WTF_EXPORT void willCreateThread();
