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. llvm-svn: 222148
