Incorrect code generated from Function.toString for get/setters in object literals

[Oliver Hunt]

If you have a function:
function f() {
   ({ set g(x){} });
}

Then f.toString will produce incorrect (non-compilable) output as it quotes the identifier string:
function f() {
   ({ set "g"(x){} });
}

Found by jsfunfuzz -- maybe i had recopmilation set to not test these cases when i was running these?

Fix appears to be

         }
     }


But I can't see why they were ever escaped strings -- is there a case i am missing where 'set "foo"(x)' would be valid?

What about getters and setters with unusual names?
