Previously if we got a DoDestroy while stopped at a breakpoint, we
would detach and then say the process had exited. This is completely
wrong, as it resulted in the python script incorrectly assuming that
the process had actually exited and trying to delete the image, when
in fact it had done no such thing.
The fix employed here is that when we get a DoDestroy, we do 3 steps:
1) initiate a termination sequence on the process
2) If we were stopped handling an exception of any kind, mask it and
let the program resume, causing the program to see the termination
request and exit on its own.
3) Let the program exit normally, and close all of our handles before
returning control back to DoDestroy.
This fixes Bug 21722 and Bug 21723.

This patch implements basic support for stopping at breakpoints
and resuming later. While a breakpoint is stopped at, LLDB will
cease to process events in the debug loop, effectively suspending
the process, and then resume later when ProcessWindows::DoResume
is called.
As a side effect, this also correctly handles the loader breakpoint
(i.e. the initial stop) so that LLDB goes through the correct state
sequence during the initial process launch.

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.
