Added new options to "target create" and "target modules add".

For "target create" you can now specify "--no-dependents" to not track down and add all dependent shared libraries. This can be handy when doing manual symbolication. Also added the "--symfile" or "-s" for short so you can specify a module and a stand alone debug info file:

(lldb) target create --symfile /tmp/a.dSYM /usr/bin/a

Added the "--symfile" option to the "target modules add" for the same reason. These all help with manualy symbolication and expose functionality that was previously only available through the public API layer.
