Lars Knoll 1cc5948839 QHash: Return void from QHashPrivate::Data::erase() 
This removes some calculations that are not required in
80% of the cases where d->erase() is being called (as
the return value is ignored). When removing lots of
elements from the hash, the ++it could loop quite a
bit until it found the next valid item in the hash.

This chain of changes combined improve the overall performance of
QHash by 10-50% depending on the operation. Deletes are twice
as fast, reads around 20% faster, inserts around 10% faster.
