Remove opt_count from SFI, which only had two real uses:
1. Detecting OSR in tests -- replaced with a stack walk in
%GetOptimizationStatus
2. Naming optimization log files -- replaced with the
optimization id
This allows us to remove a field from the SFI, moving the
bailout reason into the counters field.
As a drive-by, add optimization marker information (e.g.
marked for optimization) to the optimization status.
