xlocale patch

[David Chisnall]

Ooops, I forgot I uninstalled the subversion-freebsd package and installed subversion to work on libc++ (it would be really nice if these two could coexist, by the way...).

The updated version of the diff now passes all of the libc++ locale tests (309 files, multiple tests in each), with my copy of libc++.  I've just pushed the exception handling bits required to support std::exception_ptr to libcxxrt, so we can now build a mostly-working BSD licensed C++ stack.

For anyone that's interested, the full results of the libc++ test suite are here:

For those two lazy to click on a link, here's the summary:

****************************************************

****************************************************

The <atomic> tests all fail because the version of clang in the base system doesn't support the cxx_atomic builtins.  Not sure when these were added, but a lot of those failures should go away with a newer clang.  

Quite a few of the remaining failures are due to system headers not being C++11-aware (i.e. most of the c99 stuff should be exposed in c++11 mode).

A few tests fail when creating locales because FreeBSD doesn't have locales like en_US or fr_FR (with no encoding specified), while Darwin does (and also has locales like fr and en).  I've fixed all of the tests in the localization part of the test suite to fully specify the locale.
