The kernel tree has three identical copies of the x86 instruction decoder. Two of them are in the tools subdir. The tools subdir is supposed to be completely standalone and separate from the kernel. So having at least one copy of the kernel decoder in the tools subdir is unavoidable. However, we don't need *two* of them. Move objtool's copy of the decoder to a shared location, so that perf will also be able to use it.
