[LLVMdev] LLVM creates unterminated ELF .eh_frame sections

On BSD __register_frame also takes a single argument and therefore needs
terminating zero.
I also have a simple patch for this: adding Streamer.EmitIntValue(0, 4);
at the end of MCDwarfFrameEmitter::Emit in lib/MC/MCDwarf.cpp fixed the
issue for me.
Somebody needs to check this or similar in.
