This cleanup is designed to make the https://reviews.llvm.org/D32167 patch smaller and easier to read.
Cleanup in this patch:
Allow DWARFUnit subclasses to hand out the data that should be used when decoding data for a DIE. The information might be in .debug_info or could be in .debug_types. There is a new virtual function on DWARFUnit that each subclass must override:
virtual const lldb_private::DWARFDataExtractor &DWARFUnit::GetData() const;
This allows DWARFCompileUnit and eventually DWARFTypeUnit to hand out different data to be used when decoding the DIE information.
Add a new pure virtual function to get the size of the DWARF unit header:
virtual uint32_t DWARFUnit::GetHeaderByteSize() const = 0;
This allows DWARFCompileUnit and eventually DWARFTypeUnit to hand out different offsets where the first DIE starts when decoding DIE information from the unit.
Added a new function to DWARFDataExtractor to get the size of an offset:
size_t DWARFDataExtractor::GetDWARFSizeOfOffset() const;
Removed dead dumping and parsing code in the DWARFDebugInfo class.
Inlined a bunch of calls in DWARFUnit for accessors that were just returning integer member variables.
Renamed DWARFUnit::Size() to DWARFUnit::GetHeaderByteSize() as it clearly states what it is doing and makes more sense.

Now the codebase can use the DWARFUnit superclass. It will make it later
seamlessly work also with DWARFPartialUnit for DWZ.
This patch is only a search-and-replace easily undone, nothing interesting
in it.

*** to conform to clang-format’s LLVM style. This kind of mass change has
*** two obvious implications:
Firstly, merging this particular commit into a downstream fork may be a huge
effort. Alternatively, it may be worth merging all changes up to this commit,
performing the same reformatting operation locally, and then discarding the
merge for this particular commit. The commands used to accomplish this
reformatting were as follows (with current working directory as the root of
the repository):
find . \( -iname "*.c" -or -iname "*.cpp" -or -iname "*.h" -or -iname "*.mm" \) -exec clang-format -i {} +
find . -iname "*.py" -exec autopep8 --in-place --aggressive --aggressive {} + ;
The version of clang-format used was 3.9.0, and autopep8 was 1.2.4.
Secondly, “blame” style tools will generally point to this commit instead of
a meaningful prior commit. There are alternatives available that will attempt
to look through this change and find the appropriate prior commit. YMMV.

Added a new class called DWARFDIE that contains a DWARFCompileUnit and DWARFDebugInfoEntry so that these items always stay together.
There were many places where we just handed out DWARFDebugInfoEntry pointers and then use them with a compile unit that may or may not be the correct one. Clients outside of DWARFCompileUnit and DWARFDebugInfoEntry should all be dealing with DWARFDIE instances instead of playing with DWARFCompileUnit/DWARFDebugInfoEntry pairs manually.
This paves to the way for some modifications that are coming for DWO.
