321d6b0e67 feat: support for user-defined simp attributes in the simp tactic. 
See `RELEASES.md`

TODO: make sure `-thm` also removes `thm` from user-defined simp attributes.

6d926c7989 feat: macro expand match alternatives 
see #371

This commit does not implement all features discussed in this issue.
It has implemented it as a macro expansion. Thus, the following is
accepted
```lean
inductive StrOrNum where
  | S (s : String)
  | I (i : Int)

def StrOrNum.asString (x : StrOrNum) :=
  match x with
  | I a | S a => toString a
```
It may confuse the Lean LSP server. The `a` on `toString` shows the
information for the first alternative after expansion (i.e., `a` is an `Int`).
After expansion, we have
```
def StrOrNum.asString (x : StrOrNum) :=
  match x with
  | I a => toString a
  | S a => toString a
```

a91f92c11e feat: allow constants to be type classes 
There no reason against constants to be type classes so it is just the check in `addClass` that is needed to be modified.

1b357db3b0 fix: nasty bug at findDeclarationRangesCore? 
We must search the environment extension first, and then the builtin
table. Otherwise, the builtin declarations do not change when we
modify the files.

d954706fcf feat: ApplyNewGoals config for apply 
Lean.Meta.Tactic.apply now accepts an ApplyConfig argument.
`apply` now changes which metavariables are stored with choice
of the newGoals config.
This allows one to implement `fapply` and `eapply`.
An example of this is given in tests/lean/run/apply_tac.lean.

3193acecfa fix: flush the CoreM and MetaM caches at modifyEnv 
This fix may impact performance. Note that we don't need to flush the
cache if we are "adding" stuff to the environment. We only need to
flush the caches if the change is not monotonic. BTW, most of the
changes are monotonic. I think this is why we did not hit this bug before.

We may also move all these caches to an environment extension. It is
an easy way to make sure we preserve the cache when extending the
environment.

I tried a few benchmarks and did not notice a significant difference.

50813429b8 fix: add expected type hint 
Other tactics (e.g., `simp_all`) may try to infer the type of the
proof, and `Nat.Linear.eq_of_toNormPoly_eq` has a messy resulting type.
