Scott Graham ab01df1ffe win: Adjust thread suspend count for DumpAndCrashTargetProcess() case
Because DumpAndCrashTargetProcess() suspends the process, the thread
suspend count is one too high for all threads other than the injection
one in the thread snapshots. Compensate for this when we detect this
type of exception.
