Thread up UseCounters for a few new metrics from V8

The metrics were added in the V8 patch reviewed at
https://codereview.chromium.org/1558113002
They measure
- Each of the three deprecated Promise functions
- Two nonstandard pieces of Intl functionality
- Accesses of the RegExp.prototype.unicode getter on the prototype

BUG=v8:3785,v8:3238,v8:4633
