Allow repeat expression in event control to contain automatic terms 

The repeat expression of an event controlled non-blocking assignment is
evaluated once when the assignment is scheduled. This means there is no
risk of it being referenced when its scope has already been freed. And
hence there is no need to require the repeat expression to only contain
static terms.
