Publically expose and document qDetectCpuFeatures() and qCpuHasFeature()?

Detecting CPU features, such as SSE support, seems like a perfect feature for a cross platform library. This would take very little effort since the feature is already there and is somewhat accessible, just not fully documented. (One call in question does erroneously, in my opinion, whether a feature was requested by the compiler and whether it is supported by the CPU. These are two different things which may not be related.)
