Subject: MFC r258054: Update LLDB to upstream r194122 snapshot

  Inludes 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.
