Actually it's not that, it's that `RegsterInfo's are const elsewhere in lldb.
So mutable allows us to update `flags_type` even in that scenario.
Which is a code smell but I don't want to unpick all the const-ness elsewhere.
Just trust that we will not mutate this while someone else is trying to use it.
