ager@chromium.org 471c0d2983 Avoid callbacks to user code during error formatting in a couple of
other situations.

Do not use overwritten Object.prototype.hasOwnProperty and
Array.prototype.pop. Do not use split and join in the error formatting
implementation. They are too big to control and their generality is
not needed.
