VSCode compatibility: Find-all-references not working for special reference kinds

[ghost]

TypeScript Version: nightly (2.2.0-dev.20170214)

Code

label: while (true) {
    break label;
}

function f(x: "abc") {}
f("abc");

const x: number;
const y: number;

In VSCode, find-all-references does not work for label, "abc", or number. But document highlights does work for label and number.

Similar to #13846, but that issue is for Visual Studio.

All 3 of the mentioned ones seem to work alright today, cc @jakebailey
