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. http://groups.google.com/group/airbag-dev/browse_thread/thread/85ce85bfa8457ece git-svn-id: http://google-breakpad.googlecode.com/svn/trunk@42 4c0a9323-5329-0410-9bdc-e9ce6186880e
