<rdar://problem/12503640> Fixing an issue where the dynamic type of an Objective-C pointer changed but we still reported the one-true-definition for the previous type. This was causing issues where a variable could be reported as being of an entirely different type after an assignment

to handle an addition class of early-return instructions we find in arm code:
tail-call optimziation returns where we restore the register state from the
function entry and jump directly (not branch & link) to another function --
when that other function returns, it will return to our caller.

Previously this mid-function epilogue sequence was not being correctly detected.
We would not re-instate the prologue setup instructions for the rest of the function
so unwinds would break from that point until the end of the function.

This patch fixes an issue where if lldb fails to attach to a process (ie. invalid pid) on Linux, the process monitor thread gets stuck waiting for a signal from the attach thread, which never comes due to not being signaled. It also implements StopOpThread which is used for both attach/launch cases as I'm not aware of any special handling needed for the attach case. Also, propagate 'Error' from the Detach function instead of using a bool.

must push something on the stack for a function call or not.  In
x86, the stack pointer is decremented when the caller's pc is saved
on the stack.  In arm, the stack pointer and frame pointer don't
necessarily have to change for a function call, although most
functions need to use some stack space during their execution.

Use this information in the RegisterContextLLDB to detect invalid 
unwind scenarios more accurately.

I added the ability for a process plug-in to implement custom commands. All the lldb_private::Process plug-in has to do is override:

virtual CommandObject *
GetPluginCommandObject();

This object returned should be a multi-word command that vends LLDB commands. There is a sample implementation in ProcessGDBRemote that is hollowed out. It is intended to be used for sending a custom packet, though the body of the command execute function has yet to be implemented!

Dynamic type code must be efficient and fast. Now it is.

Added ObjC v1 support for getting the complete list of ISA values.

The main flow of the AppleObjCRuntime subclasses is now they must override "virtual bool UpdateISAToDescriptorMap_Impl();". This function will update the complete list of ISA values and create ClassDescriptorSP objects for each one. Now we have the complete list of valid ISA values which we can use for verification when doing dynamic typing.

Refactored a bunch of stuff so that the AppleObjCRuntime subclasses don't have to implement as many functions as they used to.

Change the Thread constructor over to take a Process& rather than a ProcessSP.  We can't create Threads with a NULL ProcessSP, so it makes no sense to use the SP.
Then make the Thread a Broadcaster, and get it to broadcast when the selected frame is changed (but only from the Command Line) and when Thread::ReturnFromFrame 
changes the stack.
Made the Driver use this notification to print the new thread status rather than doing it in the command.
Fixed a few places where people were setting their broadcaster class by hand rather than using the static broadcaster class call.
