Tamas Berghammer 715cbe8939 Code cleanup in preparation of adding split dwarf support 
* Remove some unused code
* Remove usage of DWARFDebugInfoEntry::Attributes where usage isn't
  reasonable
* Cleanup DWARFMappedHash with separating it to header and implementation
  file and fixing the visibility of the functions

Greg Clayton 97fbc34276 Fixed some issues where we might not have one of the new apple accelerator 
tables (like the .apple_namespaces) and it would cause us to index DWARF that
didn't need to be indexed.

Updated the MappedHash.h (generic Apple accelerator table) and the DWARF
specific one (HashedNameToDIE.h) to be up to date with the latest and
greatest hash table format.

Greg Clayton 7f99513e8f Enable all the new accelerator tables if they are present and don't manually 
index the DWARF. Also fixed an issue with memory accelerator tables with a
size of 1 where we would loop infinitely.

Added support for parsing the new .apple_namespaces section which gives us a
memory hash table for looking up namespaces.

Greg Clayton 2ed2b6bb44 Found a great optimization after speaking with Sean Callanan which cleans 
up the implementation details of the on disk hash, these changed implement
the changes in the on disk table format.

Greg Clayton 1767440a72 Convert over to the latest and greatest on disc accelerator 
hash tables. Renamed the DWARF sections to ".apple_names" and
".apple_types" until we get more buy in from other vendors.
