Update LLDB to upstream r194122 snapshot
ludes minor changes relative to upstream, for compatibility with
FreeBSD's in-tree LLVM 3.3:
- Reverted LLDB r191806, restoring use of previous API.
- Reverted part of LLDB r189317, restoring previous enum names.
- Work around missing LLVM r192504, using previous registerEHFrames API
(limited functionality).
- Removed PlatformWindows header include and init/terminate calls.
