assert.throws() and assert.doesNotThrow() blow up with a TypeError
if used with an ES6 class that extends Error.

Fixes: #3188

Without the change to lib/assert.js, the test added here results in this:

assert.js:90
  throw new assert.AssertionError({
  ^
AssertionError: expected AnotherErrorType, received TypeError: Class constructors cannot be invoked without 'new'
    at Object.<anonymous> (/tmp/node/test/parallel/test-assert.js:362:3)
    at Module._compile (module.js:399:26)
    at Object.Module._extensions..js (module.js:406:10)
    at Module.load (module.js:345:32)
    at Function.Module._load (module.js:302:12)
    at Function.Module.runMain (module.js:431:10)
    at startup (node.js:138:18)
    at node.js:976:3

With the change here to lib/assert.js, the test passes, of course.

Pre-emptive strike: Yes, the Assert API is Locked. That means: Only fixes related to security, performance, or bug fixes will be accepted. This is a bug fix. The docs say that assert.throws() can take a constructor but it blows up if it is an ES6 class constructor. This fixes that issue. (The alternative is to update the docs to indicate that ES6 classes are not OK. I'd prefer this change, although we may also want to amend the docs to indicate that the constructor should be a constructor that inherits from Error.)

LGTM. There was a problem with the centos5-64 buildbot, probably a stray process hogging a port.
