Created an attachment (id=116177)
 --> (https://bugs.webkit.org/attachment.cgi?id=116177&action=review)
patch fixing the 64bit regression

In the ArithMod fast path, the dividend value could be the final result (in case of |dividend| < |divisor|) and the result cannot be a tagged integer, so we speculate it as strict int32.
