As for lswi, lswx is supposed to cause an alignment exception in
little endian mode, but QEMU does not support it. So in case we do
not get an exception, this is an expected failure and we run the other
tests.

If fact, this is not correct: the report("partial",...) should be out
the #if..#endif body.
