2a0dc1804b feat: improve isRflProof and isRflTheorem 
The `Eq.symm` of a `rfl` theorem is a `rfl` theorem, the application
of `rfl` theorem too.

4848ad4869 feat: implement autoUnfold at simp 
Right now, it only supports the following kind of definitions
- Recursive definitions that support smart unfolding.
- Non-recursive definitions where the body is a match-expression. This
kind of definition is only unfolded if the match can be reduced.

4dd2b26e06 fix: rfl error message and corner case 
The new `rfl` slightly improves the performance for `rfl` proofs of
ground terms.
Example: `state8.lean` now takes 0.37s. It was 0.52s.

7d99f6f555 perf: isClassQuick? was incorrectly producing undef 
Then `isClassExpensive?` was being invoked too often. In some
benchmarks the performance hit was substantial. For example,
in the new test `state8.lean`. The runtime on my machine went from 2s
to 0.76s.

3cf425ba52 fix: pattern hover information 
We annotate patterns with the corresponding `Syntax` during
elaboration, and do not populate the info tree. Reason: the set of
pattern variables is not known during pattern elaboration.
