Summary: lldb should use unix socket for communication with
server on linux

As documented on the webpage, lldb on linux uses lldb-server even for local
debugging. It connects to this stub via loopback device. I believe it should
connect over a UNIX socket instead. (On Windows, named pipes are the
Explanation: For debugging a network protocol I have introduced packet loss on
the loopback device with the following command:
tc qdisc add dev lo root netem loss random 15
This introduces 15% packet loss and causes lldb to work EXTREMELY slowly
because its communication with the server stub is severely disrupted. It takes
ages to start debugging even a simple "hello world" program.
