After 8fd64d22ac (Make usage of internal
QVariant space.) change QVariant started to "inherit" movablity from
interned type.
This change fix it by interning only movable type in QVariant and by
using external allocation for not movable ones.
Obviously, this change has negative impact on QVariant it self, but
after it, QVariant will behave a lot nicer with our containers.
