ART: Fix a compiler crash for VectorizeDef() idioms.
SAD vectorization idiom (and DotProduct which was based on it)
had a bug when some instruction in the loop was visited twice
causing a compiler crash. GenerateVecOp() was called for both
the idiom root instruction and its argument in the idiom
vectorization routine; however the argument could have been
already processed by that time. It happened when two vectorization
idioms' matched patterns had a common sub-expression.
Test: test-art-target.
Test: 623-checker-loop-regressions.
