Dag-Erling Smørgrav b9c361e4af libc: Rewrite quick_exit() and at_quick_exit() using C11 atomics. 
Compiler memory barriers do not prevent the CPU from executing the code
out of order.  Switch to C11 atomics.  This also lets us get rid of the
mutex; instead, loop until the compare_exchange succeeds.

While here, change the return value of at_quick_exit() on failure to
the more traditional -1, matching atexit().
