[flang][OpenMP] The compilation fails with nowait on target construct with -g.

[abidh]

Please see the testcase below.

program nowait_reproducer
   implicit none
   real x

   !$omp target map(tofrom: x) nowait
      x = x + 1
   !$omp end target

end program nowait_reproducer

This is what I get when I try to compile it with -g.

flang -g -O0 test.f90 -fopenmp
flang-20: warning: OpenMP support in flang is still experimental [-Wexperimental-option]

  call void @__omp_offloading_10302_4986ae0__QQmain_l10(ptr %1)
