MINOR: threads: mark all_threads_mask as read_mostly

Browse source 
This variable almost never changes and is read a lot in time-critical
sections. threads_want_rdv_mask is read very often as well in
thread_harmless_end() and is almost never changed (only when someone
uses thread_isolate()). Let's move both to read_mostly.
