Show inferred types on hover

[normalser]

TypeScript Version: Version 2.1.0-dev.20160911

Code

// A *self-contained* demonstration of the problem follows...
interface Test {
    values: string[]
}

const test: Test = {
    values: [] // type: undefined[] on hover
}

When you hover values: [] in VSCode it will show type: undefined[] which in theory one could say - 'working as intended' - but would be great if type could be inferred at this level and show to user string[]

This has been brought up several times in the past, e.g. #3667, #6118, #10484.

The good news is that a fix seems to finally be near: #10610. 🎉
