analyzer: implement region_model::get_representative_path_var for labels
This fixes an ICE seen e.g. with gcc.dg/analyzer/data-model-16.c when
enabling -fdump-analyzer.
gcc/analyzer/ChangeLog:
* region-model.cc (region_model::get_representative_path_var):
Implement case RK_LABEL.
* region-model.h (label_region::get_label): New accessor.
