[PATCH 1/2] perf/x86: update Haswell PEBS event constraints

[Stephane Eranian <eranian@google.com>]

The following events support PEBS for all umasks,
thus use INTEL_EVENT_CONSTRAINT() instead of
INTEL_UEVENT_CONSTRAINT():

0xd1 MEM_LOAD_UOPS_RETIRED
0xd2 MEM_LOAD_UOPS_LLC_HIT_RETIRED
0xd3 MEM_LOAD_UOPS_LLC_MISS_RETIRED

For event 0xd0 (MEM_UOPS_RETIRED), the same is true, except
we need to distinguish precise store (umask 0x82) from load
latency events, thus we keep the breakdown per umask. But all
umasks do support PEBS.
