Add a new -a / --address argument to image show-unwind to get the
unwind instructions for a function/symbol which contains that address. Update the unwind_diagnose.py script to use this instead of doing image show-unwind by name to avoid cases where there are multiple name definitions. llvm-svn: 180079
