…6854) This PR adds a convenience for inductive predicates in `grind`. Now, give an inductive predicate `C`, `grind [C]` marks `C` terms as case-split candidates **and** `C` constructors as E-matching theorems. Here is an example: ```lean example {B S T s t} (hcond : B s) : (ifThenElse B S T, s) ==> t → (S, s) ==> t := by grind [BigStep] ``` Users can still use `grind [cases BigStep]` to only mark `C` as a case split candidate.
