* internals.h: Define MEMORY_BARRIER as empty if not defined already.
* spinlock.c (__pthread_lock): Add memory barriers.
(__pthread_unlock): Likewise.
* sysdeps/alpha/pt-machine.h (MEMORY_BARRIER): Define using mb
instruction.
(RELEASE): Not needed anymore.
(__compare_and_swap): Mark asm as modifying memory.
* sysdeps/powerpc/pt-machine.h (sync): Remove. Replace with definition
of MEMORY_BARRIER.
(__compare_and_swap): Use MEMORY_BARRIER instead of sync.
* sysdeps/sparc/sparc32/pt-machine.h (RELEASE): Not needed anymore.
(MEMORY_BARRIER): Define using stbar.
* sysdeps/sparc/sparc64/pt-machine.h (MEMORY_BARRIER): Define using
stbar.
(__compare_and_swap): Use MEMORY_BARRIER to ensure ordering.
