Strict mode syntax error when running @angular/compiler 2.3.0 in PhantomJS

[x] bug report

Current behavior
Running @angular/compiler in PhantomJS results in an error:

Uncaught SyntaxError: In strict mode code, functions can only be declared at top level or immediately within another function.

The offending code can be found in @angular/compiler/bundles/compiler.umd.js:26587:

  JitCompiler.prototype._createCompiledHostTemplate = function (compType, ngModule) {
      if (!ngModule) {
          throw new Error("Component " + stringify(compType) + " is not part of any NgModule or the module has not been imported into your module.");
      }
      var /** @type {?} */ compiledTemplate = this._compiledHostTemplateCache.get(compType);
      if (!compiledTemplate) {
          var /** @type {?} */ compMeta = this._metadataResolver.getDirectiveMetadata(compType);
          assertComponent(compMeta);
          var HostClass_1 = (function () {
              function HostClass_1() {
              }
              HostClass_1.overriddenName = identifierName(compMeta.type) + "_Host";
              return HostClass_1;
          }());
          function HostClass_tsickle_Closure_declarations() {
//        ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
              /** @type {?} */
              HostClass_1.overriddenName;
          }
          var /** @type {?} */ hostMeta = createHostComponentMeta(HostClass_1, compMeta);
          compiledTemplate = new CompiledTemplate(true, compMeta.selector, compMeta.type, hostMeta, ngModule, [compMeta.type]);
          this._compiledHostTemplateCache.set(compType, compiledTemplate);
      }
      return compiledTemplate;
  };

Expected behavior
The code should run in PhantomJS

Minimal reproduction of the problem with instructions
See tsvetomir/phantomjs-angular-2.3 for a runnable sample.

1. git clone git@github.com:tsvetomir/phantomjs-angular-2.3.git
2. cd phantomjs-angular-2.3
3. npm install
4. ./node_modules/.bin/phantomjs script.js

What is the motivation / use case for changing the behavior?
The shipped code shouldn't violate Strict Mode restrictions.

Please tell us about your environment:

• Angular version: 2.3.0

• Browser: PhantomJS 2.1.7

• Language: TypeScript 2.1

• Node (for AoT issues): 4.7

This also fails on Chromium 37, the version used on Travis CI. It runs fine in the latest Chrome.

Chromium 37.0.2062 (Ubuntu 0.0.0) ERROR
Uncaught SyntaxError: In strict mode code, functions can only be declared at top level or immediately within another function.

Getting the same error using:

• angular: 2.3.0
• angularfire2: 2.0.0-beta.6
• firebase: 3.6.2
• Firefox Developer edition: 45.0a2

When I revert to previously working version:

    "@angular/common": "~2.1.0",
    "@angular/compiler": "~2.1.0",
    "@angular/core": "~2.1.0",

the error goes away.
