Safari 10 compatibility?

Should uglify be passed the mangle: { safari10: true } option by default?

There's a little more detail about this in this glimmer-blueprint issue: glimmerjs/glimmer-blueprint#58

Yes, we should enable this option by default but we might want to consider adding this to the defaults of ember-cli-uglify until safari10 ages out...

Looks like the fix for this has been merged in ember-cli-uglify (ember-cli/ember-cli-terser#26), can we close this?

Thanks for the write up @bantic, and thanks for the reminder @acorncom!
