New issue 3342 by [email protected]: Constant folding path for string concat is not taken if one of strings is larger than ConsString::kMinLength
http://code.google.com/p/v8/issues/detail?id=3342

function f() {
  return "aaaaaaaaaaaaaaaa" + "b"
}

optimizing this function results in an inline ConsString allocation instead of folded constant. This happens because constant folding is done inside the StringAdd instruction which is not what we emit here.
