[FLANG][OpenMP] Reduction of complex with logical operation causes ICE.

[Leporacanthicus]

This program causes the compiler produce an internal error, when it ought to give an error at an earlier stage:

program main
  complex*8 a

  !$omp parallel reduction(.and. : a)
  !$omp end parallel
end program main

The error is:

error: verification of lowering to FIR failed
