Remove unused files.

* copy-diff.py was the effort to reduce the libLLVM build time
  but no longer being used because the timestamp of the generated
  .inc files should always be updated.

* tblgen-rules.mk has been splitted to llvm-tblgen-rules.mk
  and clang-tblgen-rules.mk, and tblgen-rules.mk won't be
  included by the other makefiles anymore.
