Greg Clayton cec91ef921 Fix all of the unannotated switch cases to annotate the fall through or do the right thing and break.

Jason Molenda 62e0681afb Add -Wimplicit-fallthrough command line option to clang in
the xcode project file to catch switch statements that have a
case that falls through unintentionally.

Define LLVM_FALLTHROUGH to indicate instances where a case has code
and intends to fall through.  This should be in llvm/Support/Compiler.h;
Peter Collingbourne originally checked in there (r237766), then
reverted (r237941) because he didn't have time to mark up all the
'case' statements that were intended to fall through.  I put together
a patch to get this back in llvm http://reviews.llvm.org/D17063 but
it hasn't been approved in the past week.  I added a new
lldb-private-defines.h to hold the definition for now.

Every place in lldb where there is a comment that the fall-through
is intentional, I added LLVM_FALLTHROUGH to silence the warning.
I haven't tried to identify whether the fallthrough is a bug or
not in the other places.

I haven't tried to add this to the cmake option build flags.
This warning will only work for clang.

This build cleanly (with some new warnings) on macosx with clang
under xcodebuild, but if this causes problems for people on other
configurations, I'll back it out.

Sean Callanan 9b0cfe2510 Fixed a crasher when dealing with table entries that have blank names.
This can happen with -gmodules tables when an anonymous struct is referred to.

Tamas Berghammer eb882fc1f8 Add basic fission support to SymbolFileDWARF
* Create new dwo symbol file class
* Add handling for .dwo sections
* Change indexes in SymbolFileDWARF to store compile unit offset next to
  DIE offset
* Propagate queries from dwarf compile unit to the dwo compile unit
  where applicable

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.
