commit a99127699330dce984dba38156230ab3584d0d6e

Make Intel Westmere and Nehalem event names unique
The Intel Westmere and Nehalem event lists each had two events named
MACRO_INSTS. The event names in the event lists need to be unique.
The event refererring to the Macro-fused instructions decoded (0xa6)
has been renamed MACRO_INSTS_FUSED to avoid the name collision with
MACRO_INSTS.

Fix default unit masks for Haswells
Since some of the default unit masks for Haswell events cannot be
uniquely specified by numbers, the defaults have had to be replaced
by the named ones. When the affected events are used on Haswell without
specifying unit masks after applying this patch, the default masks
are chosen correctly.
