`GetLSDAAddress` and `GetPersonalityRoutinePtrAddress` are unused and they create a bit of a problem for discontinuous functions, because the unwind plan for these consists of multiple eh_frame descriptors and (at least in theory) each of them could have a different value for these entities. We could say we only support functions for which these are always the same, or create some sort of a Address2LSDA lookup map, but I think it's better to leave this question to someone who actually needs this.
