This is a source incompatible change. There is concern that the
convenience of the implicit cast and assignment operators can lead to
misuse. Several commits have already been done that remove excess use
of the implicit cast, which is a *volatile* read every time it's used.
Users of the QAtomic* API should have to think about when they are
loading the value, and if they do or don't need the acquire memory
barrier on load. The code that people would write using this API is
meant to be multi-threaded, concurrent, and correct. The API should not
allow them to inadvertently, possibly unknowingly, shoot themselves
in the foot.

Use QAtomic*::load() and ::store() instead of the deprecated
cast, assignment, and comparison operators. These will be removed
in the near future.
The tests for these particular operators have not been changed,
though, as the change to remove the operators will also remove
the respective tests.

qttest_p4.prf was added as a convenience for Qt's own autotests in Qt4.
It enables various crufty undocumented magic, of dubious value.
Stop using it, and explicitly enable the things from it which we want.
