ca253c43e1 refactor: pattern elaboration 
We don't use the following hack anymore:
-  /- HACK: `fvarId` is not in the scope of `mvarId`
-     If this generates problems in the future, we should update the metavariable declarations. -/
-  assignExprMVar mvarId (mkFVar fvarId)

This hack was corrupting the `InfoTree`.

164f07a5e5 feat: generalize Expr.abstractRange 
It now takes free variables **and** metavariables.
This is the first step to make `mkForallFVars` and `mkLambdaFVars`
more general.

d6b782f811 chore: remove workaround 
for regression introduced by the following change

* Auto implicit behavior changed for inductive families. An auto implicit argument occurring in inductive family index is also treated as an index (IF it is not fixed, see next item)
 2022-03-08 17:58:20 -08:00

4ee131981d feat: in an inductive family the longest fixed prefix of indices is now promoted to parameters 
This modification is relevant for fixing regressions on recent changes
to the auto implicit behavior for inductive families.

The following declarations are now accepted:
```lean
inductive HasType : Fin n → Vector Ty n → Ty → Type where
  | stop : HasType 0 (ty :: ctx) ty
  | pop  : HasType k ctx ty → HasType k.succ (u :: ctx) ty

inductive Sublist : List α → List α → Prop
  | slnil : Sublist [] []
  | cons l₁ l₂ a : Sublist l₁ l₂ → Sublist l₁ (a :: l₂)
  | cons2 l₁ l₂ a : Sublist l₁ l₂ → Sublist (a :: l₁) (a :: l₂)

inductive Lst : Type u → Type u
  | nil  : Lst α
  | cons : α → Lst α → Lst α
```

TODO: universe inference for `inductive` should be improved. The
current approach is not good enough when we have auto implicits.

TODO: allow implicit fixed indices that do not depend on indices that
cannot be moved to become parameters.

7b84b4cdaa fix: improve inductive indices elaboration 
TODO: convert fixed indices to parameters. Motivation: types such as
```lean
inductive Foo : List α → Type
  | mk : Foo []
```
Users should not need to write
```lean
inductive Foo {α} : List α → Type
  | mk : Foo []
```

11cce61e4d chore: Clean up LSP folding a little 
- Wait for all terms to be elaborated before showing folding regions.
   May want to change this to support partial results.
 - Use .span to extract import statements, rather than mutually
   recursive functions.
 - Some tiny other bits of cleanup

04e60cebd1 feat: LSP code folding support 
The following constructs are foldable:
 - Sections and namespaces
 - Blocks of import/open statements
 - Multi-line commands (so mostly definitions)
 - Mutual definitions
 - Module-level doc comments
 - Top-level definition doc comments

Fixes #1012
