Impact: add new synthetic-cpuid bit definition
add X86_FEATURE_NONSTOP_TSC to the cpufeature bits - this is in
preparation of Venki's always-running-TSC patch.

Impact: cleanup
Remove duplicate #define from 'cpufeature.h'.
This also fixes the following sparse warning:
arch/x86/kernel/cpu/capflags.c:54:3: warning: Initializer entry defined twice
arch/x86/kernel/cpu/capflags.c:58:3: also defined here

Impact: None, bit reservation only
Add a synthetic TSC_RELIABLE feature bit which will be used to mark
TSC as reliable so that we could skip all the runtime checks for
TSC stablity, which have false positives in virtual environment.

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.
