Accepting request 845078 from home:aaronpuchert:llvm-next

- Update to version 0.2.0+llvm11.0.0.
  The repository that we extracted the tarball from isn't updated
  any longer. So we take the tarballs from LLVM releases instead.
- The build now uses CMake instead of a custom Python script.
- Remove dependencies on gcc, libstdc++-devel, ncurses and zlib.
- The provided package consists of LLVM bitcode files, which are
  not necessarily backwards-compatible across major versions.
  (https://llvm.org/docs/DeveloperPolicy.html#ir-backwards-compatibility)
  So we let the package provide a symbol libclc(llvmXX).
- The library files have moved from %{_libdir} to %{_datadir}.
- Make noarch: the bitcode files don't depend on the host CPU.
