Fix PR11106 by correcting a typo that has been in the code for over a year. This
would have never worked, since the element type of a vector type is never a vector type. Also fix the conditional to be more direct in checking whether EltTy is a vector type. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@141713 91177308-0d34-0410-b5e6-96231b3b80d8
