Two changes here * The main change here is to enhance the FloatIn pass so that it can float case-bindings inwards. In particular the case bindings for array indexing. * Also change the code in Simplify, to allow a case on array indexing (ie can_fail is true) to be discarded altogether if its results are unused. Lots of new comments in PrimOp about can_fail and has_side_effects Some refactoring to share the FloatBind data structure between FloatIn and FloatOut
