ed12b62e28 fix: InfoTree was missing information for (pseudo) match patterns such as x + 1. 
This kind of pattern has to be reduced to a constructor, and the
`PatternWithRef` information was being lost in the process.

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.
