Updated the pass registry with the dependency-analysis pass
Fixed slot names in MergeRules.clp and BlockDependencyCreation.clp
Updated dependency-analysis to use messages
Added the FrequencyAnalysis logic to the wavefront folder.

I also deleted the wavefront-determinant folder because it should be part of
the wavefront scheduling pass
Renamed FrequencyAnalysis.clp to WavefrontDeterminantLogic.clp

I also added the FrequencyAnalysis type to the wavefront/common folder.
