Prevent 2 unnecessary QString allocations for QString::number(0u)
QLocaleData::unsLongLongToString uses qulltoa, which will allocate a
zero-length QArrayData. Then with padding a single 0 was put in a
QString, which gets prepended to the result. By taking care of this
special case, we can now also fast-path the common case where base=10
and no flags nor precision was provided.
