d4e1299f16
Defines a new --harmony-tolength flag, and a ToLengthFlagged() runtime function, that is used where ES6 requires ToLength(), but a pre-ES6 conversion existed before. When the flag is disabled, the function uses TO_UINT32(), which is the pre-ES6 behaviour. When the flag enabled, the ES6-compliant ToLength() conversion is used. Based on a patch initially from Diego Pino <dpino@igalia.com> BUG=v8:3087 LOG=Y Review URL: https://codereview.chromium.org/1309243003 Cr-Commit-Position: refs/heads/master@{#30772}
