Fix missing double_compare_and_swap_dd_acquire_read

This matters only if AO_double_compare_and_swap[_acquire_read] actually
defined in generalize.h too.

* src/atomic_ops/generalize.h
[!AO_HAVE_double_compare_and_swap_dd_acquire_read]
(AO_double_compare_and_swap_dd_acquire_read): Define (same as definition
as auto-generated in generalize-small.h).
