Add file/line information to named events and better expr. error. 

This patch adds file and line number information to named events.
It also modifies the draw_eval_expr_wid() routine to fail with
an appropriate message for named events. This checking needs to
be pushed into the elaboration stage, but this will give a better
message than we had before.
(cherry picked from commit dff6a1ebff)
