The patch to be attached fixes a failure in fast/js/exception-sequencing-binops.html on x86-64 Linux systems with GCC 4.7.  The RHS of a % was getting evaluated before the LHS, because the toNumber() calls were not separated by a sequence point.  Pretty amusing that order of evaluation in JS depended on order of evaluation in C++, no?
