Preserve TypeScript type coercions in Closure code

[evmar]

Input:

function foo(str: string) {}
foo(<string>JSON.parse('"foo"'));

Outputs:

// @param {string} str
function foo(str) { }
foo(JSON.parse('"foo"'));

We drop the <string> so Closure doesn't know about the type cast, producing a warning.

Due to microsoft/TypeScript#6982 , I can't find any way to make TS preserve an inline Closure type coercion.

Start from this:
http://www.typescriptlang.org/Playground#src=let%20x%20%3D%20%2F**%20foo%20*%2F(3)%3B
and see if you can find some combination of parens etc. to make it work... hmm.

@martine maybe we could contribute an upstream patch?
