This is a good time to reiterate my objection: we should never suppress a
test result that shows the compiler crashing.  Our goal should be that the
compiler does not crash for any input whatsoever, and if we don't meet the
goal, it should be made visible to every tester, not hidden: that is,
don't use XFAIL to hide compiler crashes.
