Log Message:
-----------
In PhraseDictionaryNodeSCFG, use separate maps for children with terminal and non-terminal keys.  This removes the need to look up source terminals twice.  The chart decoder spends a *lot* of time in PhraseDictionaryNodeSCFG::GetChild() (approx 38% of post-startup decoding time in my target syntax test, according to callgrind), so this makes a significant difference.
