Handle frame pointer omission, (#21), part 4 (final part!): FPO stackwalker.

r=bryner
 - This change allows Airbag to properly walk win32 stacks produced by code
   built with MSVC's frame pointer omission optimization (/Oy).  This
   optimization is enabled at /O1 and /O2.
 - There too many interface and file format changes to list here.
