Initial implementation of __atomic_is_lock_free.  The input is the size of an atomic type rather than an atomic type itself just to save some implementation pain; I can change that if it seems worthwhile.

I think this is the last hook needed for <atomic> besides defines for ATOMIC_CHAR_LOCK_FREE and friends.
