[Patch] libc++: Add a default rune table

[Jonathan Roelofs]

Dan, didn't you file a PR saying that libc++ should just have its own table, and 
use that for everything?

Newlib and Bionic have this issue where some of the locale classification 
routines can't be implemented because their masks aren't proper bitmasks... This 
looks like it'll work for that.


Cheers,

Jon
