I dont know why toRemove return undefined

See original GitHub issue

https://github.com/jakubpawlowicz/clean-css/blob/master/lib/properties/optimizer.js#L133

i fix with:

if ( typeof(toRemove) != 'undefined') {
    var longhandToShorthand = toRemove.name != _name;
} else {    
 continue;
}

Seems to work in Node.js v4.4.x, but is broken in 6.0, 6.5, 6.6 and possibly others. Tested on Windows 10 x64 and Debian x64.
