    Fix warning messages in libgomp.oacc-c++/privatized-ref-[23].C testcases
    
    More workers are requested than are supported, resulting in warning messages
    as the number of workers is overridden.

            * testsuite/libgomp.oacc-c++/privatized-ref-2.C (workers, vectors):
            Reduce number of workers to 16.
            * testsuite/libgomp.oacc-c++/privatized-ref-3.C (workers, vectors):
            Likewise.
