for(var x of xs) is not handled correctly when coverage is turned on

[HCanber]

I'm getting the error Unexpected token var for this code when running with -c flag:

In file test.js:

// require('lab') and other code deleted for clarity
require('./fail.js')

In file fail.js

'use strict';
var actions=[1,2,3]
var rm={}
for (var action of actions) {
    rm[action] = true
}

If declaration of action is moved outside the for-loop it works

var action
for (action of actions) {

Looks like && node.parent.type !== 'ForOfStatement' needs to be added to https://github.com/hapijs/lab/blob/master/lib/coverage.js#L165 to get:

if (trackedTypes.indexOf(node.type) !== -1 &&
    (node.type !== 'VariableDeclaration' || (node.parent.type !== 'ForStatement' && node.parent.type !== 'ForInStatement' && node.parent.type !== 'ForOfStatement')) &&
    (node.type !== 'ExpressionStatement' || node.expression.value !== 'use strict') &&
    node.parent.type !== 'LabeledStatement') {

    tracking.push(node.loc.start.line);
    node.set('global.__$$labCov._line(\'' + filename + '\',' + node.loc.start.line + ');' + node.source());
}

Found in lab version 6.2.0
