`String.prototype.trim{Start,Left}` & `String.prototype.trim{End,Right}`

Proposal: https://github.com/sebmarkbage/ecmascript-string-left-right-trim by @sebmarkbage

Please tag this issue with the “web reality” label (because of String.prototype.trimLeft and String.prototype.trimRight). Thanks!

Let's leave this open until the proposal has been merged into the main spec, so that people looking at https://github.com/tc39/ecma262/labels/web%20reality can get a better view.
