Tagged templates emit for ES3 & 5 #1590

Currently tagged templates aren't supported when targeting ES3 or ES5. Tagged templates can be (partially) emitted like this:

foo(["A ", " B ", " C"], 1, 2);

The only difference with ES6 is (if I'm not mistaken) that the raw property on the first argument is missing. I think there are 3 solutions for this:

1. Don't allow functions that take a TemplateStringsArray as first argument, only string[]
2. Emit extra code (see below)
3. If the function takes a string[] as first argument, emit as above, otherwise (also if first argument is any), emit as below.

Alternative javascript would be:

var __template;

foo((__template = ["A ", " B ", " C"], __template.raw = ["A ", " B ", " C"], __template), 1, 2);

I'd vote for 1, since the .raw property won't be used in most cases.

I've implemented basic functionality in #1589 (without a solution for the .raw property)
