Fix GC_thread_is_registered for finished threads
(fix of commit 83c1eecd0)
A finished thread may still stay in GC_threads, but it is no longer
considered during a garbage collection phase, thus
GC_thread_is_registered() should return false in such a case.
* include/gc/gc.h [GC_THREADS] (GC_thread_is_registered): Refine
comment (describe the case when the thread is marked as finished).
* pthread_support.c (GC_thread_is_registered): Define and set me local
variable; return FALSE if KNOWN_FINISHED(me).
