/* Check that we produce sign- and zero-extended additions and
subtractions, also for 8-bit to 16-bit results. Note that we can't
eliminate compare insns, as the condition codes reflect the 32-bit
result.
This test-case is brittle, as with the presence of compare
instructions, there are several optimal instruction sequence, some of
which match the non-matcher patterns and do not contain the matching
patterns. */
