steve b1fd927acb Named events really should be expressed with PEIdent
objects in the pform,

 Handle named events within the mix of net events
 and edges. As a unified lot they get caught together.
 wait statements are broken into more complex statements
 that include a conditional.

 Do not generate NetPEvent or NetNEvent objects in
 elaboration. NetEvent, NetEvWait and NetEvProbe
 take over those functions in the netlist.
