Louis Dionne ca495e36c1 [clang] Add a new flag -fexperimental-library to enable experimental library features
Based on the discussion at [1], this patch adds a Clang flag called
-fexperimental-library that controls whether experimental library
features are provided in libc++. In essence, it links against the
experimental static archive provided by libc++ and defines a feature
that can be picked up by libc++ to enable experimental features.

This ensures that users don't start depending on experimental
(and hence unstable) features unknowingly.
