    Don't create location wrapper nodes within OpenACC clauses (testsuite
changes only)

    This fixes a GCC 11, 10, 9 regression introduced by commit
    dfd7fdca2ac17d8b823a16700525824ca312ade0 (Subversion r267272) "C++: more
    location wrapper nodes (PR c++/43064, PR c++/43486)".  But: this isn't
    intending to blame David, because back then, the problem hasn't been
visible in
    the testsuite (or else I'm sure would've been addressed right away) because
of
    our all dear friend: missing testsuite coverage.  Thus, for GCC 8, I'm
likewise
    enhancing the testsuite, without the C++ front end code changes.

    I actually had presumed that there may be an issue for OpenACC:
    <http://mid.mail-archive.com/874lb9qr2u.fsf@euler.schwinge.homeip.net>, so
here
    we are, two years (and many "wasted" hours...) later...
