Chakracore: DataView does not have correct toStringTag

[jdalton]

In Edge 14.14295 a data view has the incorrect toStringTag.

Object.prototype.toString.call(new DataView(new ArrayBuffer(23)));
// => [object Object] instead of [object DataView]

[nicolo-ribaudo]

The same is for promises:

Object.prototype.toString.call(new Promise(() => {})); // => [object Object]

Note that if you run ch.exe with the -ES6ToStringTag flag both the examples work.

[obastemur]

Update: #657 handles the both. (DataView and Promise)

Fyi -ES6ToStringTag turns on the incomplete implementation of the toStringTag feature. So fixing this the way @obastemur has done is a good thing to do before toStringTag is completed.

@abchatra and I decided this is a low risk bug fix so we'll include it in 1.2.
