Tests ch10/10.1/10.1.1_a.js, ch11/11.1/11.1.1_a.js, ch12/12.1/12.1.1_a.js of the conformance test suite for standard ECMA-402, ECMAScript Internationalization API, fail when run against the implementation currently being landed. The Intl.Collator, Intl.NumberFormat, and Intl.DateTimeFormat constructors modify properties of the RegExp constructor. The failure occurs because the use of RegExp in self-hosted code can be observed through RegExp statics due to bug 834989.

Use the new intrinsics introduced by the fix for bug 834989.

(I'd even go for removeUnicodeLocaleExtensions, myself, but that's getting long enough for length to start actually mattering, I think. :-) )
