ThisType<T> isn't respected under the --strict master option

[DanielRosenwasser]

Because the check uses compilerOptions instead of the noImplicitThis variable. 😉

Run the following example with --strict:

let x: ThisType<String> = {
    bar() {
        this.toLowerCase();
    }
}

Expected: No error
Actual: Implicit any error on this.

Already fixed in #14510.
