Not the native assembly, but a representation of the native
instructions, just create your ExecutionEngine thus:

  EngineBuilder builder(MyModule);
  TargetMachine *tm = builder.selectTarget();
  tm->Options.PrintMachineCode = 1;
  ExecutionEngine *EE = builder.create(tm);

It is quite verbose too.
