Hal Finkel bd6f1f6896 DAGCombine tryFoldToZero cannot create illegal types after type legalization
When folding sub x, x (and other similar constructs), where x is a vector, the
result is a vector of zeros. After type legalization, make sure that the input
zero elements have a legal type. This type may be larger than the result's
vector element type.

This was another bug found by llvm-stress.
