Generalize collectInductionValues (#3031)

* Generalize collectInductionValues

* Support affine transformations of loop index as induction variables

* Test for generalized induction value collection

* Neaten inductive variable finding

* Store the type of implication success when finding inductive variables

* Test that loop induction finding does not alway succeed

* Support chains of additions and branches of additions in induction variable finding

* Use c++17 for downstream compilers
