testsuite/gcc.target/cris/pr93372-2.c: Handle xpass from combine improvement

After r14-9692-g839bc42772ba7a, a sequence that actually
looks optimal is now emitted, observed at
r14-9788-gb7bd2ec73d66f7.  This caused an XPASS for this
test.  While adjusting the test, better also guard it
against regressions by checking that there are no redundant
move insns.

That's the only test that's improved to the point of
affecting test-patterns.  E.g. pr93372-5.c (which references
pr93372-2.c) is also improved, though it retains a redundant
compare insn.  (PR 93372 was about regressions from the cc0
representation; not further improvement like here, thus it's
not tagged.  Though, I did not double-check whether this
actually *was* a regression from cc0.)
