[PATCH] D143966: [DebugInfo][BPF] Add 'annotations' field for DIBasicType & DISubroutineType

@dblaikie Could you help take a look at this patch? Previously we have implemented btf_type_tag support in clang. After some discussion with gcc folks (https://lore.kernel.org/bpf/87r0w9jjoq.fsf@oracle.com/), we decided to change the dwarf format a little bit to make btf_type_tag more extensible. Currently, dwarf is used by pahole which supports the old format. @eddyz87 has implemented pahole change to support new format. So for the
time being, pahole will support both old and new format. And llvm dwarf output should also support both old and new format for a while so old pahole and new pahole should both work. Once minimum llvm requirement is lifted in linux kernel, we can remove support for old format.

Please see the above link for details. Feel free to ask any questions about rationale.
