According to OpenMP, During execution of an iteration of a worksharing-loop or a loop nest within a worksharing-loop, simd, or worksharing-loop SIMD region, a thread must not execute more than one ordered region corresponding to an ordered construct without a depend clause.
Need to report an error in this case.
