c++: display locations as C does

Browse Source 
See commit 3804aa260b.

* data/location.cc (operator<<): Display location exactly as is
done in C skeletons.
* tests/local.at (AT_LOC_PUSHDEF, AT_LOC_POPDEF): Also define
AT_FIRST_LINE, AT_LAST_LINE, AT_FIRST_COLUMN, AT_LAST_COLUMN.
* tests/actions.at (Location Print): Also check C++ skeletons.
