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.

1a04431cff New modulefile prmcw3.c avoids duplication of code between prmcw3i3.c and prmcw3i6.c. 
Implement MutatorContextCheck on Windows. Add AVERT(MutatorContext, context) in PoolAccess and other functions.
Document initialization functions MutatorContextInitFault and MutatorContextInitThread and implement them on Windows.
Add a union discriminator to MutatorContextStruct on Windows so that we don't accidentally try to get the stack pointer from a fault context, or the exception address from a thread context.
