Zachary Turner 7ae4b6de1d Only compile RegisterContextWindows_x86.cpp for x86 host architecture.
This fixes compilation failures in the 64-bit build of LLDB on Windows.

Zachary Turner 17f383d498 [ProcessWindows] Implement a RegisterContextWindows for x86.
This implements the skeleton of a RegisterContext for Windows.
In particular, this implements support only for x86 general purpose
registers.

After this patch, LLDB on Windows can perform basic debugging
operations in a single-threaded inferior process (breakpoint,
register inspection, frame select, unwinding, etc).

Zachary Turner 119767db85 [ProcessWindows] Create a TargetThreadWindows class.
This creates a TargetThreadWindows class and updates the thread
list of the Process with the main thread.  Additionally, we
fill out a few more overrides of Process base class methods.  We
do not yet update the thread list as threads are created and/or
destroyed, and we do not yet propagate stop reasons to threads as
their states change.

Zachary Turner 02862bc83a Remove the top-level DebugDriverThread in ProcessWindows.
Originally the idea was that we would queue requests to a master
thread that would dispatch them to other slave threads each
responsible for debugging an individual process.  This might make
some scenarios more scalable and responsive, but for now it seems
to be unwarranted complexity for no observable benefit.

Zachary Turner 742346a22f Decouple ProcessWindows from the Windows debug driver thread.
In the llgs world, ProcessWindows will eventually go away and
we'll implement a different protocol.  This patch decouples
ProcessWindows from the core debug loop so that this transition
will not be more difficult than it needs to be.

Zachary Turner ea66dac7cd Rename some classes in ProcessWindows.
Renamed monitor -> driver, to make clear that the implementation here
is in no way related to that of other process plugins which have also
implemented classes with similar names such as DebugMonitor.

Also created a DebugEventHandler interface, which will be used by
implementors to get notified when debugging events happen in the
inferiors.

Zachary Turner 8f21174700 Implement a framework for live debugging on Windows.
When processes are launched for debugging on Windows now, LLDB
will detect changes such as DLL loads and unloads, breakpoints,
thread creation and deletion, etc.

These notifications are not yet propagated to LLDB in a way that
LLDB understands what is happening with the process.  This only
picks up the notifications from the OS in a way that they can be
sent to LLDB with subsequent patches.

Zachary Turner 35ed13262d Teach LLDB about Windows processes.
This patch creates a simple ProcessWindows process plugin.
The only thing it knows how to do currently is create processes.
