Wrapped up the work I am going to do for now for the "add-dsym" or "target symfile add" command.

We can now do:

Specify a path to a debug symbols file:
(lldb) add-dsym <path-to-dsym>

Go and download the dSYM file for the "libunc.dylib" module in your target:
(lldb) add-dsym --shlib libunc.dylib

Go and download the dSYM given a UUID:
(lldb) add-dsym --uuid <UUID>

Go and download the dSYM file for the current frame:
(lldb) add-dsym --frame
