This patch adds support for AMD family 15h core counters. There are major changes compared to family 10h. First, there is a new perfctr msr range for up to 6 counters. Northbridge counters are separate now. This patch only adds support for core counters. Second, certain events may only be scheduled on certain counters. For this we need to extend the event scheduling and constraints. We use cpu feature flags to calculate family 15h msr address offsets. This way we later can implement a faster ALTERNATIVE() version for this.
