Avoid creating a token factor node in trivially redundant cases. This

eliminates almost one node per block in common cases.

Change the ValueList array for each node to be shared instead of individuallyallocated. Further, in the common case where a node has a single value, justreference an element from a small array. This is a small compile-time win.
