Use atomics in guard.cc / remove special casing in targets.

The PowerPC, AIX, Alpha, IA64 implementations of atomic_word.h are in no
way different from what can be achieved with the generic rewrite in
Patch 1 of this series - delete these.

Use atomics in guard.cc.
...
This provides proper definitions for _GLIBCXX_READ_MEM_BARRIER and
_GLIBCXX_WRITE_MEM_BARRIER, rewrites the guards in terms of proper
atomic extensions and removes internal uses of
_GLIBCXX_READ_MEM_BARRIER and _GLIBCXX_WRITE_MEM_BARRIER and replaces
them with equivalent atomics.
