Hopefully nobody will be stupid enough to implement a cpu without
it. Frankly, it seems safe enough given we already require SSE2.
This means the compiler can optimise away "if (!cpu_has_clflush)"
blocks.

Unnecessary. These overrides are only needed for the anticases (known
to be zero) or for some special hacks.
Stuff that have proper CPUID bits get these defined as constants via the
REQUIRED_MASK macros.
