e6ffc689aa Auto merge of #1772 - RalfJung:less-timeout-checking, r=RalfJung 
only check timeouts when a thread yields

Currently, we check for expired timeouts after each step of execution. That seems excessive. This changes the scheduler to only check for timeouts when the active thread cannot continue running any more.

`@vakaras` does this sound right? `pthread_cond_timedwait` anyway already yields, of course, since it blocks on getting the signal (or the timeout).

5bd5ea21ea Remove unwrap_none as it won't be stabilized. 
This upgrades to the latest rustc to be able to use try_insert()
instead.

c70bbea257 Move to use of thread termination hook for vector re-use, 
convert validate atomic op to use shared reference and get_raw
 instead of get_raw_mut so it can be used for validate_atomic_load as well
