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. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@185949 91177308-0d34-0410-b5e6-96231b3b80d8
