I read the source of clang. The argument of "-x" is defined in

      .Case("c", IK_C)
      .Case("cl", IK_OpenCL)
      .Case("cuda", IK_CUDA)
      .Case("c++", IK_CXX)
      .Case("objective-c", IK_ObjC)
      .Case("objective-c++", IK_ObjCXX)
      .Case("cpp-output", IK_PreprocessedC)
      .Case("assembler-with-cpp", IK_Asm)
      .Case("c++-cpp-output", IK_PreprocessedCXX)
      .Case("objective-c-cpp-output", IK_PreprocessedObjC)
      .Case("objc-cpp-output", IK_PreprocessedObjC)
      .Case("objective-c++-cpp-output", IK_PreprocessedObjCXX)
      .Case("objc++-cpp-output", IK_PreprocessedObjCXX)
      .Case("c-header", IK_C)
      .Case("cl-header", IK_OpenCL)
      .Case("objective-c-header", IK_ObjC)
      .Case("c++-header", IK_CXX)
      .Case("objective-c++-header", IK_ObjCXX)
      .Cases("ast", "pcm", IK_AST)
      .Case("ir", IK_LLVM_IR)

In my experiment, no argument except "assembler-with-cpp" can rescue
"  #-}".
