Enable generalization of all variants of CAS via fetch_compare_and_swap

* src/atomic_ops/generalize.h (AO_compare_and_swap_full,
AO_compare_and_swap_acquire, AO_compare_and_swap_release,
AO_compare_and_swap, AO_TS_COMPARE_AND_SWAP_FULL,
AO_TS_COMPARE_AND_SWAP_ACQUIRE, AO_TS_COMPARE_AND_SWAP_RELEASE,
AO_TS_COMPARE_AND_SWAP): Define (in this file) only if required for
AO_test_and_set_X generalization.
* src/atomic_ops/generalize-arithm.template
(AO_XSIZE_compare_and_swap_write, AO_XSIZE_compare_and_swap_read,
AO_XSIZE_compare_and_swap_release_write,
AO_XSIZE_compare_and_swap_acquire_read,
AO_XSIZE_compare_and_swap_dd_acquire_read): Add missing variant of
generalized template CAS primitives based fetch_compare_and_swap; add
the corresponding AO_HAVE_XSIZE_compare_and_swap_X macros.
* src/atomic_ops/generalize-arithm.h: Regenerate.
