Now that you're using setup_xfail, this should be moved into the loop
above.  Also, you should remove the fail and the continue.  You'll
want to use setup_xfail just before running the test for which you want
to turn a possible FAIL into an XFAIL.

I'm also (still) wondering how to run the testsuite to use flang
instead of gfortran since it'd be nice to test to see if the setup_xfail
actually works.  I spent just enough time looking at it last week
to convince myself that GDB's testing infrastructure currently lacks the
mechanisms to do this.  However, I could be wrong, so if someone
knows how it's done, I'd like to learn about it...
