Fix trigger for tier 1 call counting delay

The trigger was taking into account all non-tier-1 JIT invocations to delay call counting, even for those methods that are not eligible for tiering. In the AllReady benchmark, some dynamic methods were being jitted frequently enough to not allow tier 1 call counting to begin. Fixed to count only eligible methods jitted at tier 0, such that methods not eligible for tiering don't interfere with the tiering heuristics.
