[PATCH] D37677: [libc++] implement future synchronization using atomic_flag

[Dennis Luxen via Phabricator via cfe-commits]

dennis.luxen created this revision.

This task is listed in TODO.txt. The implementation swaps mutex against a spinlock based on atomic_flag. The spin lock itself is implemented as a nested class in a protected context of the associated state.
