Serban Constantinescu bf3ec9ad52 AArch64: Use LDXR/STXR instead of LDAXR/STLXR for bionic_atomic_cmpxchg() ...

The bionic_atomic_cmpxchg() API states that the cmpxchg() will be done without
explicit memory barriers. LDAXR/STLXR semantics involve half barriers for
load/store.

This patch optimises cmpxchg() by using LDXR/STXR and avoiding unnecessary half
bariers. It also fixes the clobber list for all the bionic_atomic_*() functions.
