-/// This file provides some of the support for the Liveness class. In
-/// particular, it handles the sparsity representation of the mapping
-/// between Variables and CfgNodes. The idea is that since most
-/// variables are used only within a single basic block, we can
-/// partition the variables into "local" and "global" sets. Instead of
-/// sizing and indexing vectors according to Variable::Number, we
-/// create a mapping such that global variables are mapped to low
-/// indexes that are common across nodes, and local variables are
-/// mapped to a higher index space that is shared across nodes.
