Should not suggest "caller" in strict mode as it causes TypeError

Testing #2218

function restricted()
{
    "use strict";
    restricted.ca
}

console.log(restricted());

Since we're at it, it could also highlight the caller and arguments below with a squiggly indicating a TypeError:

function restricted()
{
    "use strict";
    restricted.caller;    // throws a TypeError
    restricted.arguments; // throws a TypeError
}

console.log(restricted());

This is beyond syntax and type checking. TypeScript also doesn't error here. This would be a considerable new feature to add.

Not clear anyone is making this mistake
