Nick Kledzik aa4d2acf37 Object/llvm-objdump: allow dumping of mach-o exports trie
MachOObjectFile in lib/Object currently has no support for parsing the rebase, 
binding, and export information from the LC_DYLD_INFO load command in final 
linked mach-o images. This patch adds support for parsing the exports trie data
structure. It also adds an option to llvm-objdump to dump that export info.

I did the exports parsing first because it is the hardest. The information is 
encoded in a trie structure, but the standard ObjectFile way to inspect content 
is through iterators. So I needed to make an iterator that would do a 
non-recursive walk through the trie and maintain the concatenation of edges 
needed for the current string prefix.

I plan to add similar support in MachOObjectFile and llvm-objdump to 
parse/display the rebasing and binding info too.
