Leave variables behind when converting Types to variables
...
This is part one of addressing the present issues with emplacing type
directly where type variables should be reused. Now, when an
`Index<Type>` is converted to a variable in solving, we leave the
converted variable in the `Type`'s place. Specifically, we keep an index
to a `Cell<Type>`.
Note that this transformation is only temporary, it will be removed once
we merge this with the `Type` SoA representation, but it is needed in
the meantime as I transform the `Constrain` API to get rid of
type-emplacement.

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.

Correctly check mutual functional recursion between opaque types
...
The mutual-recursion checks does not admit types that are not function
types; because Roc is strict, only functional values can be involved in
mutual recursion. However, this check was exercised by checking the head
constructor of a type, which is not the correct way to do it. Aliases
and opaque types may in fact be function types as well, so we must chase
their actual contents.
