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. llvm-svn: 221642
