-/// \brief Equivalence classes of instructions in the ARC Model.
-///
-/// Since we do not have "instructions" to represent ARC concepts in LLVM IR,
-/// we instead operate on equivalence classes of instructions.
-///
-/// TODO: This should be split into two enums: a runtime entry point enum
-/// (possibly united with the ARCRuntimeEntrypoint class) and an enum that deals
-/// with effects of instructions in the ARC model (which would handle the notion
-/// of a User or CallOrUser).
