Need a test case that tests DWARF with .o in .a files

test/functionalities/archives:

Produces libfoo.a from a.o and b.o.  Test breaking inside functions defined
inside the libfoo.a BSD Archive.

test/make/makefile.rules:

Some additional rules to sepcify archive building.  For example:

ARCHIVE_NAME := libfoo.a
ARCHIVE_C_SOURCES := a.c b.c

ef65160016 Improve the x86_64 return value decoder to handle most structure returns.
Switch from GetReturnValue, which was hardly ever used, to GetReturnValueObject
which is much more convenient.
Return the "return value object" as a persistent variable if requested.

LLDBSwigPythonCallCommand crashes when a command script returns an object 

Add more robustness to LLDBSwigPythonCallCommand.  It should check whether the returned Python object
is a string, and only assign it as the error msg when the check holds.
Also add a regression test.

ClangASTSource::~ClangASTSource() was calling

    ClangASTContext *scratch_clang_ast_context = m_target->GetScratchClangASTContext();

which had the side effect of deleting this very ClangASTSource instance.  Not good.
Change it to

    // We are in the process of destruction, don't create clang ast context on demand
    // by passing false to Target::GetScratchClangASTContext(create_on_demand).
    ClangASTContext *scratch_clang_ast_context = m_target->GetScratchClangASTContext(false);

The Target::GetScratchClangASTContext(bool create_on_demand=true) has a new signature.

09ab4b777c Added support to the Objective-C language runtime
to find Objective-C class types by looking in the
symbol tables for the individual object files.

I did this as follows:

- I added code to SymbolFileSymtab that vends
  Clang types for symbols matching the pattern
  "_OBJC_CLASS_$_NSMyClassName," making them
  appear as Objective-C classes.  This only occurs
  in modules that do not have debug information,
  since otherwise SymbolFileDWARF would be in
  charge of looking up types.

- I made a new SymbolVendor subclass for the
  Apple Objective-C runtime that is in charge of
  making global lookups of Objective-C types.  It
  currently just sends out type lookup requests to
  the appropriate SymbolFiles, but in the future we
  will probably extend it to query the runtime more
  completely.

I also modified a testcase whose behavior is changed
by the fact that we now actually return an Objective-C
type for __NSCFString.

Fix wrong test logic in test_modules_search_paths().  Add additional exercising of 'target modules search-paths list/query".
There is a reproducible crash if 'target modules search-paths clear' is exercised during test teardown.
So we currently comment out the stmt as follows:

        # Add teardown hook to clear image-search-paths after the test.
        # rdar://problem/10501020
        # Uncomment the following to reproduce 10501020.

cbe1a331ae Fixed an issue where we might cause our test suite to exit if we end up
concatenating a string with "None" in python. Using a python format string
gets us around this by handling it gracefully.

db02f3b4f4 Fix the test suite failure. The particular line in the test case was there since the initial version
dated 2010-21-15.  The test started failure recently probably due to work done on the command parsing.
Anyway, the specific test sequence is invalid and is fixed now.

0a305db796 this patch addresses several issues with "command script" subcommands:
a) adds a new --synchronicity (-s) setting for "command script add" that allows the user to decide if scripted commands should run synchronously or asynchronously (which can make a difference in how events are handled)
 b) clears up several error messages
 c) adds a new --allow-reload (-r) setting for "command script import" that allows the user to reload a module even if it has already been imported before
 d) allows filename completion for "command script import" (much like what happens for "target create")
 e) prevents "command script add" from replacing built-in commands with scripted commands
 f) changes AddUserCommand() to take an std::string instead of a const char* (for performance reasons)
plus, it fixes an issue in "type summary add" command handling which caused several test suite errors

5009f9d501 Added support for the new ".apple_objc" accelerator tables. These tables are
in the same hashed format as the ".apple_names", but they map objective C
class names to all of the methods and class functions. We need to do this 
because in the DWARF the methods for Objective C are never contained in the
class definition, they are scattered about at the translation unit level and
they don't even have attributes that say the are contained within the class
itself. 

Added 3 new formats which can be used to display data:

    eFormatAddressInfo
    eFormatHexFloat
    eFormatInstruction
    
eFormatAddressInfo describes an address such as function+offset and file+line,
or symbol + offset, or constant data (c string, 2, 4, 8, or 16 byte constants).
The format character for this is "A", the long format is "address".

eFormatHexFloat will print out the hex float format that compilers tend to use.
The format character for this is "X", the long format is "hex float".

eFormatInstruction will print out disassembly with bytes and it will use the
current target's architecture. The format character for this is "i" (which
used to be being used for the integer format, but the integer format also has
"d", so we gave the "i" format to disassembly), the long format is 
"instruction".

Mate the lldb::FormatterChoiceCriterion enumeration private as it should have
been from the start. It is very specialized and doesn't belong in the public 
API.

aeab25c70f Add more context information to the stop-hook mechanism by displaying the stop-hook
command in the '- Hook id' header.  This should improve readbility of the 'display'
command if, for example, we have issued 'display a' and 'display b' which turn into
"target stop-hook add -o 'expr -- a'" and "target stop-hook add -o 'expr -- b'".

Plus some minor change in TestAbbreviations.py to conditionalize the platform-specific
checkings of the "image list" output.

a9dbf4325e this patch introduces a new command script import command which takes as input a filename for a Python script and imports the module contained in that file. the containing directory is added to the Python path such that dependencies are honored. also, the module may contain an __lldb_init_module(debugger,dict) function, which gets called after importing, and which can somehow initialize the module's interaction with lldb

80fdd7c0b7 Fix a problem where the stop-hook command 'frame variable g_val' produces nothing
when newly created threads were subsequently stopped due to breakpoint hit.
The stop-hook mechanism delegates to CommandInterpreter::HandleCommands() to
execuet the commands.  Make sure the execution context is switched only once
at the beginning of HandleCommands() only and don't update the context while looping
on each individual command to be executed.

the watchpoint state is changed, not only does the change propagate to all the thread instances,
it also updates a global debug state, if chosen by the DNBArchProtocol derivative.

Once implemented, the DNBArchProtocol derivative, also makes sure that when new thread comes along,
it tries to inherit from the global debug state, if it is valid.
