[PATCH] Add ApplePropertyString dump helper to Dwarf.{h|cpp}.

[David Blaikie]

Sure, looks fine.

(this sort of thing can probably go in with usage - so it's tested/exercised/executed - rather than just dead code. It's a tricky balance in terms of commit granularity, though usually a change like this is isolated enough from the (presumably) dwarf dumping code that'll be using it that it doesn't complicate the review)
