localstorage: disable warning about tautological comparison
When building with gcc 6.1.1, there is a warning like this:
plugin.cpp:152:126: error: self-comparison always evaluates to true [-Werror=tautological-compare]
DEFINE_OBJECT_VTABLE(QV4::QQmlSqlDatabaseWrapper);
In the definition of DEFINE_OBJECT_VTABLE, the comparison
&classname::SuperClass::static_vtbl == &Object::static_vtbl ? 0 : &classname::SuperClass::static_vtbl.vTable
will be done at runtime. Maybe the macro could somehow do
that at compile time (or maybe the compiler will optimize
it away after detecting that the result is constant);
but for now, this warning breaks the build.
Task-number: QTBUG-53373
