due to RTTI worries since llvm and clang don't use RTTI, but I was able to 
switch back with no issues as far as I can tell. Once the RTTI issue wasn't
an issue, we were looking for a way to properly track weak pointers to objects
to solve some of the threading issues we have been running into which naturally
led us back to std::tr1::weak_ptr. We also wanted the ability to make a shared 
pointer from just a pointer, which is also easily solved using the 
std::tr1::enable_shared_from_this class. 

The main reason for this move back is so we can start properly having weak
references to objects. Currently a lldb_private::Thread class has a refrence
to its parent lldb_private::Process. This doesn't work well when we now hand
out a SBThread object that contains a shared pointer to a lldb_private::Thread
as this SBThread can be held onto by external clients and if they end up
using one of these objects we can easily crash.

So the next task is to start adopting std::tr1::weak_ptr where ever it makes
sense which we can do with lldb_private::Debugger, lldb_private::Target,
lldb_private::Process, lldb_private::Thread, lldb_private::StackFrame, and
many more objects now that they are no longer using intrusive ref counted
pointer objects (you can't do std::tr1::weak_ptr functionality with intrusive
pointers).

from the SBTarget and SBModule interfaces. Also added many python properties
for easier access to many things from many SB objects.

for when we enable the assisted layout.

All of the commands now get globbed into a single line.

lldb.target, lldb.process, lldb.thread and lldb.frame now get initialized with
empty SBTarget, SBProcess, SBThread and SBFrame objects when they don't contain
anything. 

llvm-svn: 149166

will ask ExternalASTSource objects to help laying out a type. This is needed
because the DWARF typically doesn't contain alignement or packing attribute
values, and we need to be able to match up types that the compiler uses
in expressions.

Emit the message about putting ' -- ' between the end of command options and the raw input conditionally,
that is, only if the command object does not want completion.  An example is the "settings set" command.

Also added a few utilty functions that can be enabled for debugging issues
with modules staying around too long when external clients still have references
to them.

watching for errors from pthread_mutex_destroy () (usually "Resource
busy" errors for when you have a mutex locked and try to destroy
it), and pthread_mutex_lock, and pthread_mutex_unlock (usually for
trying to lock an invalid mutex that might have possible already
been freed).

ExecutionContext objects have shared pointers to Target, Process, Thread
and Frame objects and they can end up being held onto for too long.

(lldb) settings show frame-format
