Not sure why this was added seems like original import from apple repos had this but AArch64 procedure call standard doesnt have it as you said. This also means compiler should never emit a dwarf instruction with reg num 32. GDB doesnt use PC reg num either and i dont remember seeing any special use of this register number anywhere in LLDB. May be ask @clayborg or @jasonmolenda  they seems to have written the code according to commit log.
