The fix makes sense, but I think we still need to figure out what's the deal with green dragon. I can check out [the arm64 watchpoint failure](https://green.lab.llvm.org/job/llvm.org/view/LLDB/job/as-lldb-cmake/18969/testReport/junit/lldb-api/functionalities_reverse-execution/TestReverseContinueWatchpoints_py/) (eventually), but we might need help with the x86_64 failures. Judging by the error message, I'd say that the x86 debugserver reports some extra registers, which then turn out to be unreadable (@jasonmolenda does that sound plausible?). Maybe we should skip unreadable registers?
