x86 msr_index.h: Define MSR_MISC_FEATURE_CONTROL

Browse Source 
This non-architectural MSR has disable bits
for various prefetchers on modern processors.

While these bits are generally touched only by the BIOS,
say, via BIOS SETUP, it is useful to dump them
when examining options that can alter performance.
