865317 - Allow a useful NodePool::Enumerator to be constructed for an empty CC graph

Status: RESOLVED FIXED

(Core :: XPCOM, defect)

Description

[Andrew McCreight [:mccr8]]

In incremental CC, we want to create a NodePool::Enumerator before we've added anything to the graph, to keep track of the nodes we've built already.  mBlocks starts out as NULL, though, so this doesn't work.  By making mFirstBlock a reference, then when a node does get added, it will be updated.
