  Log Message:
  -----------
  [NewPM] Don't run before pass instrumentation on required passes

This allows those instrumentation to log when they decide to skip a
pass. This provides extra helpful info for optnone functions and also
will help with opt-bisect.

Have OptNoneInstrumentation print when it skips due to seeing optnone.
