! Test that the driver correctly reports diagnostics from the prescanner, no
! matter what driver action/phase is run. We need this test as Flang currently
! has no central API for managing the diagnostics. For this reason the driver
! needs to make sure that the diagnostics are indeed issued (rather that relying
! on some DiagnosticsEngine).
