ArrayBoundCheckerV2: don't arbitrarily warn about indexing before the 0-index of a symbolic region.  In many cases that isn't really the base offset.

This patch adds modeling of strcmp() to the CString checker. Validates inputs are not NULL and are real C strings, then does the comparison and binds the proper return value. Unit tests included.

Make sure that Modules can track their object file offsets correctly to
allow opening of sub object files (like the "__commpage" on darwin).

Modified the Platforms to be able to launch processes. The first part of this
move is the platform soon will become the entity that launches your program
and when it does, it uses a new ProcessLaunchInfo class which encapsulates
all process launching settings. This simplifies the internal APIs needed for
launching. I want to slowly phase out process launching from the process
classes, so for now we can still launch just as we used to, but eventually
the platform is the object that should do the launching.

Modified the Host::LaunchProcess in the MacOSX Host.mm to correctly be able
to launch processes with all of the new eLaunchFlag settings. Modified any
code that was manually launching processes to use the Host::LaunchProcess
functions.

Fixed an issue where lldb_private::Args had implicitly defined copy 
constructors that could do the wrong thing. This has now been fixed by adding
an appropriate copy constructor and assignment operator.

Make sure we don't add empty ModuleSP entries to a module list.

Fixed the commpage module creation on MacOSX, but we still need to train
the MacOSX dynamic loader to not get rid of it when it doesn't have an entry
in the all image infos.

Abstracted many more calls from in ProcessGDBRemote down into the 
GDBRemoteCommunicationClient subclass to make the classes cleaner and more
efficient.

Fixed the default iOS ARM register context to be correct and also added support
for targets that don't support the qThreadStopInfo packet by selecting the
current thread (only if needed) and then sending a stop reply packet.

Debugserver can now start up with a --unix-socket (-u for short) and can 
then bind to port zero and send the port it bound to to a listening process
on the other end. This allows the GDB remote platform to spawn new GDB server
instances (debugserver) to allow platform debugging.

Use debug info in the IR to find the directory/file:line:col. Each time that location changes, bump a counter.

Unlike the existing profiling system, we don't try to look at argv[], and thusly don't require main() to be present in the IR. This matches GCC's technique where you specify the profiling flag when producing each .o file.

The runtime library is minimal, currently just calling printf at program shutdown time. The API is designed to make it possible to emit GCOV data later on.
