Unify implementations of __builtin_mem_*_fence and __sync_synchronize.
* builtins.c (expand_builtin_mem_thread_fence): Remove.
(expand_builtin_mem_signal_fence): Remove.
(expand_builtin_atomic_thread_fence): Use expand_mem_thread_fence.
(expand_builtin_sync_synchronize): Likewise.
(expand_builtin_atomic_signal_fence): Use expand_mem_signal_fence.
* optabs.c (expand_asm_memory_barrier): Split out from
expand_builtin_mem_signal_fence.
(expand_mem_thread_fence): New, a combination of code from
expand_builtin_mem_thread_fence and expand_builtin_sync_synchronize.
(expand_mem_signal_fence): Moved and renamed from
expand_builtin_mem_signal_fence.
(expand_atomic_exchange): Use expand_mem_thread_fence.
(expand_atomic_load, expand_atomic_store): Likewise.
* expr.h, optabs.h: Update decls.
