perf/x86: Implement 64-bit counter support for IBS
This patch implements 64 bit counter support for IBS. The
sampling period is no longer limited to the hw counter width.
The functions perf_event_set_period() and
perf_event_try_update() can be used as generic functions. They
can replace similar code that is duplicate across architectures.
