0ee4d7ca06 Indirect formatted scanning through the scanstate. 
This will allow us to reuse the scanning protocol with an arbitrary area
scanning function (replacing traceFormatScan) in order to implement
formatted object walking without an extra segment method.

Don't insist on scanning only grey segments: we want to be able to
reuse the scan protocol for walking, when the segments are black.

60bf7320e2 Document the event parameters. 
Split event ArenaAccess into ArenaAccessBegin and ArenaAccessEnd to avoid the need for the count field.
New events SegReclaim and SegScan.
Delete some redundant events: AMCFinish (PoolFinish), AMCFix, AMCFixForward, AMCFixInPlace (TraceFix), AMCGenCreate (GenInit), AMCGenDestroy (GenFinish), AMCInit (PoolInitAMC), AMCReclaim (SegReclaim), AMCScanBegin, AMCScanEnd (SegScan), ArenaWriteFaults (ArenaAccessBegin), PoolInitMV, TraceScanSeg (SegScan).
Add result code field to events ArenaAllocFail, CommitLimitSet, SegAllocFail.
Remove arena field from events PoolInitAMS, PoolInitMFS, PoolInitMVFF (already appeared in generic PoolInit event).

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.
