Currently, Flang can generate no-loop kernels for all OpenMP target kernels in the program if the flags -fopenmp-assume-teams-oversubscription or -fopenmp-assume-threads-oversubscription are set. If we add an additional parameter, we can choose in the future which OpenMP kernels should be generated as no-loop kernels. This PR doesn't modify current behavior of oversubscription flags.
