PR libstdc++/65913
* builtins.c (fold_builtin_atomic_always_lock_free): Handle fake
pointers that encode the alignment of the object.

PR libstdc++/65913
* include/bits/atomic_base.h (__atomic_base<_TTp>::is_lock_free(),
__atomic_base<_PTp*>::is_lock_free()): Call the built-in with the
immediate pointer value, not a variable.
* include/std/atomic (atomic<T>::is_lock_free()): Likewise.
* testsuite/29_atomics/atomic/65913.cc: New.
