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.
