[PATCH] libc++: Add option to disable access to the global filesystem namespace

[Ed Schouten]

Hi Jonathan,

As you proposed, I have inverted the logic. We now have a flag _LIBCPP_HAS_GLOBAL_FILESYSTEM_NAMESPACE. I temporarily added -D_LIBCPP_HAS_GLOBAL_FILESYSTEM_NAMESPACE to test/libcxx/test/config.py, so I've been able to mark all the tests that require the global filesystem namespace.

I won't add anything permanent to config.py yet. There may still be a number of other flags I'll need to add. My plan is to tailor config.py as soon as libc++ builds entirely.
