Optimize QBitArray::count(bool)
Ever since 76e0223619da02911d02813961ef631a5e02d826, qPopulationCount
was extracted from QBitArray and moved elsewhere. That unfortunately
meant that the 24-bit loads are completely useless, since
qPopulationCount always operates on 32 bits.
Instead, do a full loop on 32-bit and then do 16-bit and finally 8-bit
(for which there are qPopulationCount overloads).
