Title: Use goog.array.ASSUME_NATIVE_FUNCTIONS define

If set to `true`, the native implementation of array functions are used and the pure js implementation is removed from the build.
But because we (conditionally) support IE 7-8 (`ol.LEGACY_IE_SUPPORT`) we cannot add this define in `buildcfg/ol.json`
