JSTests:
- stress/intl-locale.js: Added.

Enable Intl.Locale feature with flag.
- test262/expectations.yaml:
Mark known failures.
None of these should be specific to Intl.Locale.
Source/JavaScriptCore:
This patch implements the recent ECMA-402 feature Intl.Locale.
This is effectively a wrapper class for all the pieces of uloc.h that ECMA-402 cares about.
(If we used the C++ API, there's a LocaleBuilder that would make this much easier, but in sticking to the C API,
it's basically an object that has an ICU localeID as data and uloc_* functions as methods / getters.
Furthermore, there's no way to modify said data, so every method / getter can be lazy and cache its result.)
Usage example:
locale = new Intl.Locale('ja', { region: 'JP', calendar: 'japanese', numeric: false })
"ja-JP-u-ca-japanese-kn-false"
locale.baseName
"ja-JP"
Intl.Locale can be used anywhere that Intl APIs accept locale strings as input parameters,
and is moreover hoped to be the class by which future Web APIs will handle the current locale.
This feature is runtime-guarded by the useIntlLocale option.
