dump_cmds_json: Output groups

Browse source 
Also output `pass->location.{file_name,line,function_name}()`.
If no group is given (i.e. it is "unknown"), attempt to automatically apply a group.
If we have source locations, this is based on path to the source file.
If we do not have source locations, try to match on the pass name instead.
