Allocate QML defined properties without extra room
QV4::MemberData is used to allocate storage for QML defined properties.
QV4::MemberData::reallocate() is multiplying each allocation by two
as a growth strategy. This is a waste of memory for QML defined properties.
This commits extends the QV4::MemberData with an additional method
to allow exactly sized allocations.
