This is first part if ICV tracking support in OpenMPOpt. Things that are included in this pathc:

- ICV information definition (not complete) in `OMPKinds.def`.
- OpenMP-specific information cache based on Attributor's InformationCache. This should should make it easier to share information between them.
- possibility of running the Attributor through `runAttributor()`.
- AAICVTracking AbstractAttribute with basic tracking.

Since there are a lot of changes to agree up on, I left out the deduplication part for now. There are 2 possible places where that can be done: current deduplication functions, or within AAICVTracking's manifest.

This can also be treated as a RFC.
