9c78d29a2f Fix parsing issue 
I made this follow the test, but that may not actually be the desired
approach.

So the question is what the region of an identifier in a pattern is.
Previously this was

    { x }
      ^

Using the new parser it became

    { x }
      ^^

Which this commit corrects to the old state by using the region from an
AssignedField.

a5cf0fc505 Parse field access after record literal 
e.g. `{ x: 4 }.x` now parses. This is of limited practical use of course
but I would expect this to work based on the signature of `.x`.

502021d955 Always parse type signatures in let blocks. 
Formerly, this would not parse

    foo : Int
    foo = 4

While this would

    bar = 3
    foo : Int
    foo = 4

Now, the first def can also be a type annotation.

This change performs some code duplication. This can probably be
abstracted/unified, but I'm not sure how to do that in a clean way.
