Andrew Litteken 9e73f7c8d2 [IRSim] Adding basic implementation of llvm-sim.
This is a similarity visualization tool that accepts a Module and
passes it to the IRSimilarityIdentifier.  The resulting SimilarityGroups
are output in a JSON file.

Tests are found in test/tools/llvm-sim and check for the file not found,
a bad module, and that the JSON is created correctly.

Reviewers: paquette, jroelofs, MaskRay

Recommit of: 15645d044bcfe2a0f63156048b302f997a717688 to fix linking
errors and GN build system.
