Do a static_cast in bit-blasts that are UB
Without this, building Qt and Qt applications fails with GCC 8.
The errors look like this:
writing to an object of type ‘class QPointer<QQuickPointerHandler>’ with no trivial copy-assignment; use copy-assignment or copy-initialization instead [-Werror=class-memaccess]
Task-number: QTBUG-65691
