[turbofan] Also recognize 'type' === typeof x.

So far we only recognized

  typeof x == 'type'
  typeof x != 'type'
  typeof x === 'type'
  typeof x !== 'type'

but some people seem to prefer it the other way around, i.e.

  'type' == typeof x
  'type' != typeof x
  'type' === typeof x
  'type' !== typeof x

as spotted in some Ember.js code, so we should obviously handle that as
well and reduce it to a quick check on x instead of calling the TypeOf
builtin and comparing the resulting string.
