e68e448070 fix: convert inductive type instance implicit parameters to implicit when building SizeOf instance 
It is better for TC resolution since the parameter can be inferred by
typing constraints, and it addresses issue #1373

a62949c49b refactor: add type LevelMVarId (and abbreviation LMarId) 
Motivation: make sure we do not mixup metavariable ids for
expression and universe level.

5e877b115b feat: improve calc tactic 
> Heather suggested changing the calc tactic (not the term) such that if
the final RHS does not defeq match the goal RHS, it returns a final
inequality as a subgoal.

c46ef56ac7 perf: avoid blowup at deriving Repr 
The fix is not perfect. I just avoided inlining in some builtin `Repr` instances.
The actual problem is at `ElimDeadBranches.lean`.

d1f0db7072 fix: resumePostponed backtracking 
Note that test for issue #1200 broke.
The bug fixed by this commit was allowing the example to be elaborated
correctly :(
Initially, the type of the discriminant is not available, and
`.none (α:=α)` can only be elaborated when the expected type is of the
form `C ...`. Lean then tries to elaborate the alternatives, learn
that the discriminant should be `Option ?m`, and fails because the
patterns still have metavariables after elaboration. Before the bug
fix, `resumePostpone` was **not** restoring the metavariable context,
and the assingnment would stay there. With this information, Lean
can now elaborate `.none (α:=α)`.
Although the bug had a positive impact in this case, it produced
incorrect behavior in other examples.
The fixed example looks reasonable. Thus, we will not reopen
issue #1200

4c707d3b3c feat: use binop% to elaborate %-applications 
Motivation: make sure the behavior is consistent with other arithmetic
operators.

This commit also removes the instance
```
instance : HMod (Fin n) Nat (Fin n) where
  hMod := Fin.modn
```
because we have a coercion from `Fin n` to `Nat`.
Thus, given `a : Fin n` and `b : Nat`, `a % b` is ambiguous.
