Added the ability to specify a preference for mangled or demangled to Mangled::GetName.
Changed one place where mangled was prefered in GetName.
The Dynamic loader should look up the target of a stub by mangled name if it exists.

removing it didn't cause any performance loss, and leaks were showing up
when run under instruments when we tried to re-use the buffer. We are now leak
free and still just as performant.

I'm not sure when multiple threads enter this method but a race-condition
causing a crash in malloc can be reproduced with this little script:

echo file $(which lldb) > cmd
echo "run\nbreak set -n main\nrun\nexit" >> cmd
lldb -s cmd

It may need a few runs before it crashes though.
