[PATCH] x86-64: x86-64 add Intel Core related PMU MSRs definitions



Add o the x86-64 tree a bunch of MSRs related to performance
monitoring for the processors based on Intel Core microarchitecture.
It also adds some architectural MSRs for PEBS. A similar patch for i386 will
follow.

changelog:
	- add Intel Precise-Event Based sampling (PEBS) related MSR
	- add Intel Data Save (DS) Area related MSR
	- add Intel Core microarchitecure performance counter MSRs
