please, add tests for:

foo([var a = const {}]) {}

and for

foo() {
  var a = const [];
  var b = const {};
}

bonus point for something like:

foo([var a = const [ const { 'a': const [ 1, 2, 3 ] } ]]) {}

And what about const Foo() constructs overall?

Done. And I reverted the case for NewExpression.

'const'.
I reverted this, NewExpression does not have constKeyword, this case needs more
investigation.
