This makes the two most-often used QTypedArrayData::allocate() -- the ones for char (for QByteArray) and char16_t (for QString) -- go to specialized versions, which have much simpler code. After all, multiplications by 1 are quite trivial. I didn't check whether an LTO compiler was const-propagating the sizes in inlined calls from qstring.cpp and qbytearray.cpp. But not everyone uses LTO, so this benefits everyone, in a very hot path, for minimal cost.
