x86/mce: Add Local MCE definitions

Add required definitions to support Local Machine Check
Exceptions.

Historically, machine check exceptions on Intel x86 processors
have been broadcast to all logical processors in the system.
Upcoming CPUs will support an opt-in mechanism to request some
machine check exceptions be delivered to a single logical
processor experiencing the fault.

See http://www.intel.com/sdm

 Volume 3, System Programming Guide,
chapter 15 for more information on MSRs and documentation on
Local MCE.
