Polyfill: Remove weeks and days arguments from ISODateSurpasses

[catamorphism]

The polyfill always calls ISODateSurpasses with weeks and days equal to 0, and the arguments are only used when they're not equal to 0, so remove them altogether. (In the spec, ISODateSurpasses is called with non-zero weeks and days, but the polyfill does an optimization that means it's not called with non-zero weeks or days.)
