Detailed Description

Represents dependencies between instructions.

This class is a wrapper of SUnits and its dependencies to manipulate back-edges in a natural way. Currently it only supports back-edges via PHI, which are expressed as anti-dependencies in the original DAG. FIXME: Support any other loop-carried dependencies
