Bug for this-type in literal object type

[andy-hanson]

This code causes an error:

type X<A> = {x: A}

interface Foo {
    // works
    a(): X<this>
    // does not work
    b(): {x: this}
}

Output:

foo.ts(7,11): error TS2526: A 'this' type is available only in a non-static member of a class or interface.

It errors if the object type is defined inline, but works for a typedef.

This is by design. See discussion here.
