  Changed paths:
    M llvm/test/CodeGen/X86/or-with-overflow.ll

  Log Message:
  -----------
  [X86] or-with-overflow.ll - adjust or_i64_ri constant to not constant fold the icmp

Better KnownBits handling of the icmp and/or an upcoming USUBSAT fold would constant fold this test away and prevent us testing for a cleared overflow flag.
