2b3fbbb8d3 New pool method poolsegpoolgen gets the pool generation for a segment. (this allows the segment whiten and reclaim methods not to need to know the pool class.)

577b32d481 Cherry-pick change 192595 from custom/cet/main, removing mps_addr_object. this function failed to solve the problem of decoding the stack on 64-bit windows, because the stack may need to be decoded after an mps assertion failure, in which case the arena lock is held and mps_addr_object cannot be called. we eventually solved the problem in a different way (using mps_arena_postmortem) and mps_addr_object is no longer used.

38614c785e Make shield assertions robust against deep checking -- when shieldcover is called from shieldraise there is one unsynced segment that has not yet been queued. record this fact in a new queuepending flag in the shield structure. 
Remove incorrect shield assertion "shield->depth == 0 || shield->suspended" -- depth may be increased without suspending the mutator if the segment did not need protecting.
