Would it be possible to implement CG(zend_linecol) in addition to
 CG(zend_lineno)? As far I can see, this is a missing prerequisite for
 Xdebug to report more fine-grained code coverage, for instance.

I've been thinking about this also, and would find this useful for some profiler/visualization purposes and perhaps for inclusion in errors.

Unless we put this inside each opcode, I'm not sure it'd help xdebug too 
much. And I'm not sure it is worth inflating the opcodes.
Also, I'm not sure scanner now knows enough to do it - though maybe it 
can be made to know it.

 Did anyone look into this yet? I still think that it would be beneficial
 to have this information.
