This operation was classified as a binary operation in the widening logic for some reason (clearly, untested). It is in fact a unary operation. Add a RUN line to a test to exercise this for x86. Note that again the vector widening strategy doesn't regress anything and in one case removes a totally unecessary instruction that we couldn't avoid when promoting the element type. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@212257 91177308-0d34-0410-b5e6-96231b3b80d8
