The registerization code needs the function to end in a RET, even if that RET is actually unreachable. The liveness code needs to avoid such unreachable RETs. It had a special case for final RET after JMP, but no case for final RET after UNDEF. Instead of expanding the special cases, let fixjmp - which already knows what is and is not reachable definitively - mark the unreachable RET so that the liveness code can identify it.

Binary Distribution Notes
If you have just untarred a binary Go distribution, you need to set
the environment variable $GOROOT to the full path of the go
directory (the one containing this README). You can omit the
variable if you unpack it into /usr/local/go, or if you rebuild
from sources by running all.bash (see doc/install.html).
You should also add the Go binary directory $GOROOT/bin
to your shell's path.
For example, if you extracted the tar file into $HOME/go, you might
put the following in your .profile:
export GOROOT=$HOME/go
export PATH=$PATH:$GOROOT/bin
See doc/install.html for more details.
