Make sure self-recursive checks only happen after typechecking
Programs like

```
after : ({} -> a), ({} -> b) -> ({} -> b)

fx = after (\{} -> {}) \{} -> if Bool.true then fx {} else {}
```

are legal because they always decay to functions, even if they may not
look like functions syntactically. Rather than using a syntactic check
to check for illegally-recursive functions, we should only perform such
checks after we know the types of values.

Implement obligation checking for the Eq ability
Every type can have `Eq.isEq` derived for it, as long as

- it does not transitively contain a function
- it does not transitively contain a floating point value
- it does not transitively contain an opaque type that does not support
  `Eq`

Construct exhaustiveness branches with condition, not branch, variable
Previously we would construct the shapes of unions used in the pattern
tree for exhaustiveness checking using the type of the branch patterns,
rather than the type of the condition variable. Clearly we want to
always use the condition variable, otherwise some branches will be
seen as exhaustive, when they are not!

To do this, we now index into the condition variable while refying the
patterns to build the tree for exhaustiveness checking.
