Fix an issue in SimplifySetCC() specific to vector comparisons. When folding X == X we need to check getBooleanContents() to determine if the result is a vector of ones or a vector of negative ones. I tried creating a test case, but the problem seems to only be exposed on a much older version of clang (around r144500). rdar://10923049 git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@153966 91177308-0d34-0410-b5e6-96231b3b80d8
