Omnibus Dependency API Updates

Signed-off-by: Schuyler Eldridge <schuyler.eldridge@ibm.com>

This adds a prettyPrint method to the DependencyManager to enable
textual visualization of the TransformLikes that a DependencyManager
determines need to be run.

This also cleans up the GraphViz visualization with better edge
coloring and now uses the `name` method when labeling graphviz nodes.

This makes a change to the Dependency API that breaks chisel3. This
needs to [skip chisel tests], but is fixed with

Allow self renames

Change the behavior of RenameMap.completeTarget so that self-renames
do not silently *not* happen. Previously, requests to self-rename
would be ignored unless they were packaged in a sequences of renames
that included a self-rename.

Change renames to be recorded distinctly so that multiple requests to
rename to the same thing will now deduplicate. Previously, these
renames would be recorded multiple times. This change was required
because allowing self-renames exposed a bug in InferWidthsAnnosSpec
due to multiple renames.

These changes benefit the situation where you rightly want to do a
self-rename. Namely, when doing module duplication (with the
EliminateTargetPaths transform).

Do not record the same rename multiple times

* Consume NoDedupMemAnnotations in ResolveMemoryReference

The ComponentName being pointed to by the annotation no longer exists
after ReplaceSeqMems so we should consume the annotations

* Support renaming in ReplaceMemMacros
