Extend alignment of QArrayData to std::max_align_t in allocationHEADdev
Make stricter alignment requirements for the allocated header This strict alignment allows reallocateUnaligned() to property account for the padding occurring in cases when alignof(QArrayData) < alignof(T) <= alignof(std::max_align_t), which happens to be the case on e.g. 32-bit platforms with specific alignment requirements. This adds 4 bytes (the difference between alignof(std::max_align_t) and sizeof(QArrayData)) of overhead for QString, QByteArray and certain QLists on 32-bit systems.
