New package: llvm12-12.0.0

Distro changes since 11.0: - html docs are now included (except lldb where they are broken) - manpages are now included - enabled linker build id - libcxx(abi), libunwind, libomp are now built as subpackages - disabled clangd on ppc32 (crashes assembler) - template cleanups Cross fixes by Leah.
