Both print_local_APIC (used when apic=debug kernel param is set) and
cpu_debug code missed support for some extended APIC registers that
I'd like to see.
This adds support to show:
- extended APIC feature register
- extended APIC control register
- extended LVT registers
[ Impact: print more debug info ]

Impact: New register definitions only
CMCI means support for raising an interrupt on a corrected machine
check event instead of having to poll for it. It's a new feature in
Intel Nehalem CPUs available on some machine check banks.
For details see the IA32 SDM Vol3a 14.5
Define the registers for it as a preparation for further patches.

Change header guards named "ASM_X86__*" to "_ASM_X86_*" since:
a. the double underscore is ugly and pointless.
b. no leading underscore violates namespace constraints.
