Bob Wilson 78f006acdf Change CodeGen/ARM/2009-11-02-NegativeLane.ll to use 16-bit vector elements
so that it will continue to test what it was meant to test when I commit a
separate change for better support of BUILD_VECTOR and VECTOR_SHUFFLE for Neon.
Fix a DAG combiner crash exposed by this test change.
