SIMD: Refactor the constants to be actual bit values
... instead of being the bit numbers. This allows us to test more than
one feature at a time with qCpuHasFeature (see commit about the Haswell
architecture features). The drawback is that we won't be able to handle
more than 63 different CPU features, though we're likely quite far from
it (x86 currently has only 36 features).
