Subject: [PATCH 0/4] perf/x86: simplify PEBS event constraint management

This patchkit revamps the PEBS tables on most Intel CPUs, both simplifying
and fixing a couple of problems on Haswell processors:
 - All PEBS event supported
 - data address and data source is now reported correctly for all events

We simplify the tables by using the fact that non-PEBS event when used
in PEBS mode do not generate any PEBS records , thus they are safe to use.
This helps simplify the PEBS event constraints because they do not need
to list all suported PEBS events anymore. They only need to list
the special PEBS events, such as precise store and load latency.
This avoid some issues where the kernel is missing some PEBS events.
