Use isTrueWhenEqual and isFalseWhenEqual instead of assuming that
SimplifyICmpOperands will simplify such cases to EQ or NE. This makes the correcntess of the code independent on SimplifyICmpOperands doing certain simplifications. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@102927 91177308-0d34-0410-b5e6-96231b3b80d8
