perf_counter, x86: Implement generalized cache event types, add Atom support

Fill in core2_hw_cache_event_id[] with the Atom model specific events.

The events can be used in all the tools via the -e (--event) parameter,
for example "-e l1-misses" or -"-e l2-accesses" or "-e l2-write-misses".

( Note: these are straight from the Intel manuals - not tested yet.)
