This commit replace the old CBackendPass with a standalone tool:
revng-decompile.
This pass at the moment runs the three stages of decompilation:
- CFG restructuring
- Beautify GHAST
- C Code generation
This library replaces the old AddIRSerializationMarkers, cleaning up a
lot of historcal baggage, merging Liveness and MarkAnalysis, and
adopting a more accurate naming across all the codebase.
