7f7822d4ab Segment class gcseg no longer implements hardware barriers; these are implemented by new subclass mutatorseg, which is now used everywhere that gcseg was used formerly. the idea is that in a future change mrgrefseg will inherit from gcseg instead of mutatorseg.

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.
