go/parser has switched from reporting no position for the end of a
broken file to reporting an invalid position. This broke on of our tests
that contains broken code. Change the test case as a result.

In cases like:
type myInt int
const (
a = 1
b myInt = 2
)
var foo myInt = <>
We now prefer "b" over "a" since b's type matches the expected type
exactly.

For *ast.Ident completion requests, this checks the parent node to
see if the token begins a statement and then based on the path adds
possible keyword completion candidates. The test lists some cases where
this approach cannot provide completion candidates.
The biggest thing missing is keywords for file level declarations

Add some extra smarts when evaluating untyped constants as completion
candidates. Previously we called types.Default() on the expected type
and candidate type, but this loses the untypedness of an untyped
constant which prevents it from being assignable to any type or named
type other than the untyped constant's default type.
Note that the added logic does not take into account the untyped
constant's value, so you will still get some false positive
completions (e.g. suggesting an untyped negative integer constant when
only a uint would do). Unfortunately go/types doesn't provide a way of
answering the question "is this *types.Const assignable to this
types.Type" since types.AssignableTo only considers a constant's type,
not its value.

Calculate expected type in the following cases:
- switch case statements
- index expressions (e.g. []int{}[<>] or map[string]int{}[<>])
- slice expressions (e.g. []int{}[1:<>])
- channel send statements
- channel receive expression
We now also prefer type names in type switch clauses and type asserts.

ranking of results in binary expressions, and import cycles.
