Make dynamic type detection faster by using the AST metadata to help out and allow us not to complete types when we don't need to.
After running "purge" on a MacOSX system, the Xcode variables view now populates more than 3x faster with this fix.

Also added C++11 enum test cases to cover enums as int8_t, int16_t int32_t, int64_t, uint8_t, uint16_t, uint32_t, and uint64_t both for DWARF and dSYM cases. The DWARF being emitted by clang is missing the enum integer type, but the code is now ready to accept and deal with the integral type if it is supplied.

LLDB wasn't printing the names for negative enums. Fixed the signed extraction of enumerators and how they were registered with clang's type system.

- resolved circular dependency issue by making liblldb depend directly on LLDBWrapPython.cpp
- removed use of '..' for relative directories -- ninja doesn't like this
- fixed build-order problem

DWARF with .o files now uses 40-60% less memory!
Big fixes include:
- Change line table internal representation to contain "file addresses". Since each line table is owned by a compile unit that is owned by a module, it makes address translation into lldb_private::Address easy to do when needed.
- Removed linked address members/methods from lldb_private::Section and lldb_private::Address
- lldb_private::LineTable can now relink itself using a FileRangeMap to make it easier to re-link line tables in the future
- Added ObjectFile::ClearSymtab() so that we can get rid of the object file symbol tables after we parse them once since they are not needed and kept memory allocated for no reason
- Moved the m_sections_ap (std::auto_ptr to section list) and m_symtab_ap (std::auto_ptr to the lldb_private::Symtab) out of each of the ObjectFile subclasses and put it into lldb_private::ObjectFile.
- Changed how the debug map is parsed and stored to be able to:
- Lazily parse the debug map for each object file
- not require the address map for a .o file until debug information is linked for a .o file

in a core file if it didn't start at the beginning of a memory segment.
I added more sophisticated kernel location code to DynamicLoaderDarwinKernel
and removed the simple one in ProcessMachCore. Unfortunately the kernel
DynamicLoader doesn't get a chance to search around in memory unless there's
a hint that this might be a kernel debug session. It was easy ot make the
kernel location code static in DynamicLoaderDarwinKernel and call it from
ProcessMachCore on the start of the session, so that's what I did.

and use it to keep from doing the OS Plugin UpdateThreadList while destroying, since
if that does anything that requires the API lock it may deadlock against whoever is
running the Process::Destroy.

Also removed the use of llvm::raw_string_ostream as it wasn't needed.
Also fixed a crasher that could occur when the following line returned a C string tied to a local variable:
return OS.str().c_str();
I am guessing "static std::string buf;" was supposed to get assigned to "OS.str()" and then have "buf.c_str()" returned.
Modified the non-apple version code to cache its value and not recompute the version every time.

- make LLDB version number match Clang (and the Debian package)
- use the same revision detection magic that Clang uses to report SVN/Git revisions
- update test case as per above

- made sure we tell Clang not to try to
complete the type since it can't be
completed from its origin any more; and
- fixed a silly bug where we tried to
forget about the original decl's origins
rather than the deported decl's origin.
These produced some crashes in ptr_refs,
especially under libgmalloc.

Fixed an issue with clang 500's new way to represent static class variables where it emits a DW_TAG_member with a DW_AT_external(0x01) attribute and no DW_AT_data_member_location.

SymbolFileDWARF code:
- If a class is being uniqued to another copy of itself
and the method lists don't match exactly, take a slow
path and at least unique the methods that they have
in common.
- Sort name_to_die maps before querying them. This
would otherwise result in uniquing failures because
looking up a name in a map that contains it would
often fail.
- Tolerate classes in other symbol files in the case
of debugging with .o files rather than with a
.dSYM. We used to assume that the classes being
uniqued were in the same symbol file, causing
unpredictable results.
This will dramatically reduce the number of cases where
a function does not have a valid DeclContext.

plugin.dynamic-loader.darwin-kernel.load-kexts setting, don't print
any messages about loading the kexts (which isn't being done) and
don't read the Mach-O headers out of memory (which can be slow and
they're not being used for anything at this point).
