[X86] Convert ==/!= comparisons with -1 for checking undef in shuffle lowering to comparisons of <0 or >=0. While there do the same for other kinds of index checks that can just check for greater than 0. No functional change intended. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@273788 91177308-0d34-0410-b5e6-96231b3b80d8
