Jason McDonald 94a7d439f2 Remove Q_ASSERT from qatomicint/pointer autotests
Some code in these tests is not intended to be executed, but rather to
detect compiler warnings.  Instead of having an obscure fatal error if
this code is run in a debug build, it now has a clear fatal error if run
in any build.
