* diagnostic-manager.cc
(diagnostic_manager::prune_for_sm_diagnostic)<case EK_CALL_EDGE>:
Refactor to work with edges without callgraph edge.
(diagnostic_manager::prune_for_sm_diagnostic)<case EK_RETURN_EDGE>:
Likewise.

(egion_model::update_for_call_superedge): Get the underlying gcall and
update for gcall.
(region_model::update_for_return_superedge): Likewise.
* region-model.h (region_model::update_for_gcall): New decl.
(region_model::update_for_return_gcall): New decl.
* state-purge.cc (state_purge_per_ssa_name::process_point): Update to
work with calls without underlying cgraph edge.
