963033a1f8 Use signatures in type checking 
For now only considers constants, e.g.

    foo : Int -> Int
    foo = \x -> x

But not yet rigid type variables, like `a -> a`

This kind of requires an additional variant of TypeAnnotation:

    TypedDef(
        &'a Loc<Pattern<'a>>,
        Loc<TypeAnnotation<'a>>,
        &'a Loc<Expr<'a>>,
    ),

Because otherwise combining the information from an annotation and its
succeeding body definition is hard. Currently, this variant is created
in an ad-hoc way. Perhaps this can be done during parsing?

Next, like previous commits, I've just copied the code for let, and
effectively added an additional constraint. There should be a way to
reduce the duplication again.

e8d2fadc85 fiddle with whitespace parsing in annotations 
This is still not correct for formatting (can drop newlines) but works for now.
Not sure how to do better, perhaps conditionally add the whitespace to the first term?

f05734e8c2 return rigid type variables 
Turns out this is simpler: we can return a SendMap<Lowercase, Variable>,
replacing the Rigids return value (a ImMap<Lowercase, Type>) which can
be recovered from the SendMap.
