Optimize contrcuction of variant of type pointer.
Constructing a variant of a pointer type was previously quite slow:
QVariant had no information it was a pointer. It had to create a
QVariant::PrivateShared, ask the QMetaType for a constructor (slow as it
involve locking mutextes) and allocate a pointer.
By detecting a pointer in qVariantFromValue, we can store the pointer
value dirrectly in the Variant union. We then avoid 2 allocations,
and the expensive locking in QMetaType::construct
