Adds new APIs for querying sets of modules in an InstanceGraph:
- modules: the set of all modules
- reachableModules: set of modules reachable from the main/top
- unreachableModules: set of modules not reachable from the main/top

Change InstanceGraph.staticInstanceCount to include modules with no
instances. Previously, these modules would just not be included.

* Change FIRRTL-internal API, affecting only one corner case
* Make API more "DWIM" and consistent with other methods
* Add test cases for findInstancesInHierarchy
* Update Scaladoc

(#1186)
* Replace instance analysis code with InstanceGraph API calls
* Add convenience implicits for using TargetTokens as safe boxed strings
|
|
|
|
This fixes all Scaladoc warnings except for those trying to link to
Java.

Formerly #865
Major Code Changes/Features Added:
Added Target trait as replacement for Named
Added TargetToken as token in building Target
Added GenericTarget as a catch-all Target
Added CircuitTarget, ModuleTarget, ReferenceTarget, and InstanceTarget
Added ResolvePaths annotation
Added EliminateTargetPaths (and helper class DuplicationHelper)
Updated Dedup to work with instance annotations
Updated RenameMap to work with instance annotations
DCE & ConstantProp extend ResolveAnnotationPaths

This reverts commit 7e2f787e125227dc389d5cf1d09717748ecfed2e.

Added Target, which now supports Instance Annotations. See #865 for details.

* add FoldADD to const prop, add yosys miter tests
* add option for verilog compiler without optimizations
* rename FoldLogicalOp to FoldCommutativeOp
* add GetNamespace and RenameModules, GetNamespace stores namespace as a ModuleNamespaceAnnotation
* add constant propagation for Tail DoPrims
* add scaladocs for MinimumLowFirrtlOptimization and yosysExpectFalure/Success, add constant propagation for Head DoPrim
* add legalize pass to MinimumLowFirrtlOptimizations, use constPropBitExtract in legalize pass

* Added grouping pass
* Added InfoMagnet and infomappers

Massive refactoring to WiringTransform with the use of a new EulerTour
class to speed things up via fast least common ancestor (LCA) queries.
Changes include (but are not limited to):
* Use lowest common ancestor when wiring
* Add EulerTour class with naive and Berkman-Vishkin RMQ
* Adds LCA method for Instance Graph
* Enables "Two Sources" using "Top" wiring test as this is now valid
* Remove TopAnnotation from WiringTransform
* Represent WiringTransform sink as `Seq[Named]`
* Remove WiringUtils.countInstances, fix imports
* Support sources under sinks in WiringTransform
* Enable internal module wiring
* Support Wiring of Aggregates
