The default settings generated by Angular CLI in src/polyfills.ts had the following stuff commented out. With the comments removed, it mostly works -- but see at the end.

/** IE9, IE10 and IE11 requires all of the following polyfills. **/
import 'core-js/es6/symbol';
import 'core-js/es6/object';
import 'core-js/es6/function';
import 'core-js/es6/parse-int';
import 'core-js/es6/parse-float';
import 'core-js/es6/number';
import 'core-js/es6/math';
import 'core-js/es6/string';
import 'core-js/es6/date';
import 'core-js/es6/array';
import 'core-js/es6/regexp';
import 'core-js/es6/map';
import 'core-js/es6/weak-map';
import 'core-js/es6/set';

/** IE10 and IE11 requires the following for NgClass support on SVG elements */
import 'classlist.js'; // Run npm install --save classlist.js.

/** IE10 and IE11 requires the following for the Reflect API. */
import 'core-js/es6/reflect';

Following this, there was still a residual issue. It was removed by adding the following, see angular/angular-cli#4128

import 'core-js/es7/array';
