Add a --fix option for wrap-regex

[not-an-aardvark]

I'm using Node v6.4.0 and ESLint v3.4.0.

It would be useful to have an autofix option for the wrap-regex rule. The fixer would simply wrap all regular expression literals with parentheses, if they aren't parenthesized already.

var hasFoo = /foo/.test(myStr);

// gets fixed to:

var hasFoo = (/foo/).test(myStr);

We would need to ensure that adding parentheses doesn't cause the regex to be interpreted as a function parameter (like with no-unexpected-multiline). However, I don't think this is an issue, because in scenarios like this, the regex is parsed as a division operator anyway:

var unrelated = 'foo' // <-- no semicolon
/regex/.test('bar');

// This is a SyntaxError even before parentheses are added,
// because `/` is parsed as a division operator.

I would be willing to add this if the issue is accepted.
