exports.hasOwnProperty(p) won’t work in case exports has a null prototype or has overridden hasOwnProperty(…): microsoft/TypeScript#37013 and #92.

We should probably get in the habit of saving off intrinsics like this (i.e. var hasOwn = Object.prototype.hasOwnProperty and hasOwn.call(exports, p)), but we don't necessarily want to have to introduce a __hasOwn helper for that kind of case.

That said, its up to @weswigham if he wants to take on that change for tslib right now, since it's out of scope for this change.

That said, we do call Object.hasOwnProperty.call in __importStar below this.
