[INTL] some valid language tags cause errors in Intl constructors

[Andy VanWagoner]

The tests for language tag handling in the kangax compat tables[1][2] fail in JSC on some valid language tags:

cmn-hans-cn-t-ca-u-ca-x-t-u
aa-a-foo-x-a-foo-bar
x-en-u-foo
x-en-u-foo-u-bar

Implementations in Firefox, Chrome, and Edge pass these tests.

I know where the problem is, and can submit a patch for this.

If it's handy, I suggest quoting the relevant part of the spec here, or providing a url to it.
