8225be2f0e feat: ensure projections are not reducing at DiscrTree V (simpleReduce := true) 
Now, the `simp` discrimination tree does not perform `iota` nor reduce
projections.

5f38a483f2 fix: congr tactic 
`MVarId.congr?` and `MVarId.hcongr?` should return `none` if an
exception is thrown while applying congruence theorem.

`MVarId.hcongr?` should try `eq_of_heq` before trying to apply
`hcongr` theorem.

closes #1787

BTW: Lean 4 `congr` tactic is applying `assumption`. Lean 3 version does not.

c98b3a5388 fix: add local Hashable instance (fixes #1737) 
When inductives are indirectly mutually recursive, say `inductive T | t
(args: List T)` instead of `inductive T | t (arg : T)`, Lean would fail
to find an instance of Hashable for `T` because it was not yet defined.

This commit makes sure that the deriving handler adds a needed Hashable T
instance to the local scope so that Hashable.hash can be resolved
recursively.
