Make it easier to declare asm or preprocessed outputs to c/c++ tasks 

The following can be used to add asm outputs to a c++ task (gcc):

        from waflib import Task
        from waflib.TaskGen import feature, after_method
        @feature('cxx')
        @after_method('process_source')
        def add_asm_outputs(self):
                for tsk in self.compiled_tasks:
                        node2 = tsk.outputs[0].change_ext('.s')
                        tsk.env.append_value('CXXFLAGS', '-Wa,-adhln=%s' % node2.abspath())
                        tsk.outputs.append(node2)
