Add test case to preprocessor.

Browse Source 
- This enables some tests which had been unexpectedly disabled in
earlier test.
- Tests to show issue QTCREATORBUG-7225.
- Tests which validates somehow behavior of preprocessor for
QTCREATORBUG-7217: the test passes, so the problem is likely not in the
startExpandingMacro() notification.
