#1881 should fix the Date failures.

The x86 failures are almost certainly due to floating point issues but I can't reproduce them locally with a x86 build...

test262/test/built-ins/Date/prototype/setMonth/this-value-valid-date-arg-non-finite.js:39: unexpected error: Test262Error: setMonth(NaN) [[DateValue]] Expected SameValue(«1467331200000», «NaN») to be true
test262/test/built-ins/Date/prototype/setMonth/this-value-valid-date-arg-non-finite.js:39: previous error: Test262Error: setMonth(NaN) [[DateValue]] Expected SameValue(«1467356400000», «NaN») to be true

Note the two values, 1467331200000 and 1467356400000. I'll cherry-pick #1881 and see if that fixes them.

edit: it does
