Visit all Ideal Nodes

[Bharadwaj Yadavalli]

Is there a way to visit every node in the ideal graph at any given time 
during the C2 compilation process other than walking the graph starting 
at its root?

I was wondering if maintaining a vector of pointers to all nodes created 
(or Node_Array) - in the Compiler object - is considered (or known to 
be) a performance drag.

Thanks,

Bharadwaj
