[PR88484] OpenACC wait directive without wait argument but with async clause

We don't correctly handle "#pragma acc wait async (a)" for "a >= 0", handling
as a no-op whereas it should enqueue the appropriate wait operations on
"async (a)".

        libgomp/
        PR libgomp/88484
        * oacc-parallel.c (GOACC_wait): Correct handling for "async >= 0".
        * testsuite/libgomp.oacc-c-c++-common/asyncwait-nop-1.c: New file.

Added:
    trunk/libgomp/testsuite/libgomp.oacc-c-c++-common/asyncwait-nop-1.c
