Optimize QString::insert()
When the insertion position is not beyond end(), call
resize() instead of expand(), which fills the new size
with spaces, which, however would just be overwritten
by the following memmove().
Add some Q_UNLIKELY to indicate that we strongly
expect the resize() case to be the more common.
