Widen some suppressions to better cover XP and Vista.
Widen some suppressions to better cover XP and Vista.

- i#529: Vista uses data16 test, so the instruction doesn't match.
- i#709: We get a slightly different stack on XP with
  RtlDestroyEnvironment instead of LdrShutdownProcess.
- i#18: The call stack with symbols is slightly different, and we don't
  have a mod+offs suppression at all.
