ES6 Change: Unify handling of RegExp CharacterClassEscapes \w and \W and Word...

At the May 2016 TC-39 meeting, it was agreed that we should make slight changes to the way CharacterClassEscapes \w and \W work with case insensitive unicode regular expressions. As part of that change, it was agreed that the \b and \B Word Assertions would be aligned with \w and \W. The resolution is to have the \w CharacterClass in a unicode, case insensitive RegExp (ui flags) includes lower case and upper case ASCII letters, digits 0 through 9, underscore (_), and the two Unicode characters Small Latin Sharp S (\u017f) and the Kelvin sign (\u212a). The \W CharacterClass in a unicode, case insensitive RegExp includes all the characters not in the \w CharacterClass. The \b and \B Word Assertions for unicode, case insensitive RegExp should track what is going on for \w & \W. The discussion can be found at:

Patch r=me Will this cause some apparent failures in the kangax or ECMA test suites? If so, I think we should hold off until the tests are updated.

It does cause a kangax failure. I fully expect that is also causes a test262 failure. I'll hold off landing until the spec is updated as well as the tests.
