b5f0feabae Wrapped up the work I am going to do for now for the "add-dsym" or "target symfile add" command.
We can now do:

Specify a path to a debug symbols file:
(lldb) add-dsym <path-to-dsym>

Go and download the dSYM file for the "libunc.dylib" module in your target:
(lldb) add-dsym --shlib libunc.dylib

Go and download the dSYM given a UUID:
(lldb) add-dsym --uuid <UUID>

Go and download the dSYM file for the current frame:
(lldb) add-dsym --frame

3d654b3044 Brought LLDB top-of-tree into sync with LLVM/Clang
top-of-tree.  Removed all local patches and llvm.zip.

The intent is that fron now on top-of-tree will
always build against LLVM/Clang top-of-tree, and
that problems building will be resolved as they
occur.  Stable release branches of LLDB can be
constructed as needed and linked to specific release
branches of LLVM/Clang.

2cb5e527f6 Fixed a problem where persistent variables did
not correctly store the contents of Objective-C
classes.  This was due to a combination of
factors:

  1) Types were only being completed if we were
     looking inside them for specific ivars
     (using FindExternalVisibleDeclsByName). 
     We now look the complete type up at every
     FindExternalLexicalDecls.

  2) Even if the types were completed properly,
     ValueObjectConstResult overrode the type
     of every ValueObject using the complete type
     for its class from the debug information.
     Superclasses of complete classes are not
     guaranteed to be complete.  Although "frame
     variable" uses the debug information,
     the expression parser does now piece together
     complete types at every level (as described
     in Bullet 1), so I provided a way for the
     expression parser to prevent overriding.

  3) Type sizes were being miscomputed by
     ClangASTContext.  It ignored the ISA pointer
     and only counted fields.  We now correctly
     count the ISA in the size of an object.

9e6cffc9fd A patch that allows for mach-o architectures to be specified as "<number>-<number>" where the first number is the cpu type and the second is the cpu subtype. Also added code to allow use of mach-o architectures that aren't in our tables so that symbolication and static file introspection (crashlogs) can work with them.

bc47dfcba2 This patch is part of ongoing work to extract type
information from the Objective-C runtime.

This patch takes the old AppleObjCSymbolVendor and
replaces it with an AppleObjCTypeVendor, which is
much more lightweight.  Specifically, the SymbolVendor
needs to pretend that there is a backing symbol file
for the Types it vends, whereas a TypeVendor only
vends bare ClangASTTypes.  These ClangASTTypes only
need to exist in an ASTContext.

The ClangASTSource now falls back to the runtime's
TypeVendor (if one exists) if the debug information
doesn't find a complete type for a particular
Objective-C interface.  The runtime's TypeVendor
maintains an ASTContext full of types it knows about,
and re-uses the ISA-based type query information used
by the ValueObjects.

Currently, the runtime's TypeVendor doesn't provide
useful answers because we haven't yet implemented a
way to iterate across all ISAs contained in the target
process's runtime.  That's the next step.

513c6bb88c Initial check-in of "fancy" inlined stepping. Doesn't do anything useful unless you switch LLDB_FANCY_INLINED_STEPPING to true. With that
on, basic inlined stepping works, including step-over of inlined functions.  But for some as yet mysterious reason i386 debugging gets an
assert and dies immediately.  So for now its off.

4c05410f8f Made it so changes to the prompt via "settings set prompt" get noticed by the command line.
Added the ability for OptionValueString objects to take flags. The only flag is currently for parsing escape sequences. Not the prompt string can have escape characters translate which will allow colors in the prompt.

Added functions to Args that will parse the escape sequences in a string, and also re-encode the escape sequences for display. This was looted from other parts of LLDB (the Debugger::FormatString() function).

7036425c59 <rdar://problem/12202862>
Added a fix for incorrect dynamic typing. Before when asking if a C++ class could be dynamic, we would answer yes for incomplete C++ classes. This turned out to have issues where if a class was not virtual, yet had its first ivar be an instance of a virtual class, we would incorrectly say that a class was virtual and we would downcast it to be a pointer to the first ivar. We now ask the class to complete itself prior to answering the question. We need to test the effects on memory of this change prior to submission. It is the safest and best fix, but it does have a potential downside of higher memory consumption.

This can end up being used to get the string contents of a text file and could end up not being NULL terminated. I added accessors to get the file contents raw, or with a null terminator.

1f7460716b <rdar://problem/11757916>
Make breakpoint setting by file and line much more efficient by only looking for inlined breakpoint locations if we are setting a breakpoint in anything but a source implementation file. Implementing this complex for a many reasons. Turns out that parsing compile units lazily had some issues with respect to how we need to do things with DWARF in .o files. So the fixes in the checkin for this makes these changes:
- Add a new setting called "target.inline-breakpoint-strategy" which can be set to "never", "always", or "headers". "never" will never try and set any inlined breakpoints (fastest). "always" always looks for inlined breakpoint locations (slowest, but most accurate). "headers", which is the default setting, will only look for inlined breakpoint locations if the breakpoint is set in what are consudered to be header files, which is realy defined as "not in an implementation source file". 
- modify the breakpoint setting by file and line to check the current "target.inline-breakpoint-strategy" setting and act accordingly
- Modify compile units to be able to get their language and other info lazily. This allows us to create compile units from the debug map and not have to fill all of the details in, and then lazily discover this information as we go on debuggging. This is needed to avoid parsing all .o files when setting breakpoints in implementation only files (no inlines). Otherwise we would need to parse the .o file, the object file (mach-o in our case) and the symbol file (DWARF in the object file) just to see what the compile unit was.
- modify the "SymbolFileDWARFDebugMap" to subclass lldb_private::Module so that the virtual "GetObjectFile()" and "GetSymbolVendor()" functions can be intercepted when the .o file contenst are later lazilly needed. Prior to this fix, when we first instantiated the "SymbolFileDWARFDebugMap" class, we would also make modules, object files and symbol files for every .o file in the debug map because we needed to fix up the sections in the .o files with information that is in the executable debug map. Now we lazily do this in the DebugMapModule::GetObjectFile()

Cleaned up header includes a bit as well.

c5041918dd Added SBDebugger's log callbacks to Python-land
- Tweaked a parameter name in SBDebugger.h so my typemap will catch it;
- Added a SBDebugger.Create(bool, callback, baton) to the swig interface;
- Added SBDebugger.SetLoggingCallback to the swig interface;
- Added a callback utility function for log callbacks;
- Guard against Py_None on both callback utility functions;

- Added a FIXME to the SBDebugger API test;
- Added a __del__() stub for SBDebugger.

We need to be able to get both the log callback and baton from an
SBDebugger if we want to protect against memory leaks (or make the user
responsible for holding another reference to the callback).
Additionally, it's impossible to revert from a callback-backed log
mechanism to a file-backed log mechanism.

892943f9dd Cope with the case where the user-supplied callbacks want the watchpoint itself to be disabled!
Previously we put a WatchpointSentry object within StopInfo.cpp to disable-and-then-enable the watchpoint itself
while we are performing the actions associated with the triggered watchpoint, which can cause the user-initiated
watchpoint disabling action to be negated.

Add a test case to verify that a watchpoint can be disabled during the callbacks.

Added a new "interpreter" properties to encapsulate any properties for the command interpreter. Right now this contains only "expand-regex-aliases", so you can now enable (disabled by default) the echoing of the command that a regular expression alias expands to:

(lldb) b main
Breakpoint created: 1: name = 'main', locations = 1

Note that the expanded regular expression command wasn't shown by default. You can enable it if you want to:

(lldb) settings set interpreter.expand-regex-aliases true
(lldb) b main
breakpoint set --name 'main'
Breakpoint created: 1: name = 'main', locations = 1

Also enabled auto completion for enumeration option values (OptionValueEnumeration) and for boolean option values (OptionValueBoolean).

Fixed auto completion for settings names when nothing has been type (it should show all settings).
