Modified Files:
        src/sys/arch/x86/include: specialreg.h
        src/sys/arch/x86/x86: identcpu.c

Log Message:
Declare the MSR_VIA_ACE values as macros, and use a consistent naming,
similar to the rest of the file.

I'm wondering if I'm not fixing a huge bug here. The ECX8 value we were
using was wrong: ECX8 is bit 1, not bit 0. Bit 0 is ALTINST, an alternate
ISA, which is now known to be backdoored.

So it looks like we were explicitly enabling the backdoor.

Not tested, because I don't have a VIA cpu.
