Optimize string additions
QV4::String can now either hold a pointer to a QStringData,
or a pair of pointers to a left and right string. This
reduces the overhead of an addition to allocating a new
GC'ed object.
To avoid huge chains of linked strings, we use a depth counter,
and flatten the string once the depth reaches 16.
