LLDB-mi have 3 threads. 1. Wait for input. 2. Process commands. 3. Process events. This revision merges 1 & 2. Same thread waits on input and then process the command. This way, no synchronization is needed between first and 2nd. Also it is easy to check when to exit. A lot of code will redundant and will be cleaned up gradually. All lldb-mi tests pass with gcc and clang as test compiler. Also did minimal testing on command line and works ok. The "quit" and "-gdb-exit" command close the application without needing any further return. Reviewed in http://reviews.llvm.org/D7746. llvm-svn: 230003
