Atomic op cleanup.

Replaced VM-local macros for barrier and CAS calls with the actual
versions provided by cutils.

 ATOMIC_CMP_SWAP(addr,old,new) --> android_atomic_release_cas(old,new,addr)

 MEM_BARRIER --> ANDROID_MEMBAR_FULL

Renamed android_quasiatomic* to dvmQuasiAtomic*.

Didn't change how anything works, just the names.
