Returns the index of a mismatch between s1 & s2, failing when
length is reached. Note that we return 'length' upon failure
(array content matches) and a 0-based index upon success.
Use this as a faster opEquals. Also provides the basis for a
faster opCmp, since the index of the first mismatched character
can be used to determine the return value
