Remove the basic Math.sumPrecise polyfill

Browse Source 
This is already polyfilled properly via core-js in `legacy` builds, and the only reason that it wasn't already removed is that the tests (on the bots) use the "modern" builds and Chrome didn't support `Math.sumPrecise` until now; see https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/Math/sumPrecise#browser_compatibility
