Avoid matching the same pattern statement twice

r262275 allowed pattern matching on pattern statements. Testing for SVE on more benchmarks showed a case where this interacted badly with 14/n. The new over-widening detection could narrow a COND_EXPR A to another COND_EXPR B, which mixed_size_cond could then match. This was working as expected.
