Address review comments on r290392: - Don't break using '-mllvm -disable-llvm-optzns' (yet). - Don't add support for '-mllvm -disable-llvm-passes'. This is important for LLVM 4 as we haven't yet really told folks this is coming. I'll add release notes about this. I've also added some explicit testing of this so its more obvious what is happening here. llvm-svn: 291850

// We support a CC1 option for disabling LLVM's passes.
// RUN: %clang -O2 -Xclang -disable-llvm-passes -### %s 2>&1 \
// RUN: | FileCheck --check-prefix=DISABLED %s
// DISABLED: -cc1
Another fix for r291850 because there are apparently targets which add "-mllvm" flags to the CC1 invocation (notably, Hexagon seems to hit this). llvm-svn: 291881
