It appears that this change caused flakiness in LayoutTest js/dom/encode-URI-test.html and JSC test mozilla-tests.yaml/ecma/GlobalObject/15.1.2.5-2.js See: https://bugs.webkit.org/show_bug.cgi?id=167020 https://build.webkit.org/builders/Apple%20El%20Capitan%20Release%20JSC%20%28Tests%29/builds/11637

Ah, i see. I changed k and length to unsigned. Previously, it was `int`. I thought it is not intentional. But it is intentional because we would like to check the condition like `k <= length - 6` even if `length` is less than 6. I'll change this part, add comment about it, and land this patch.
