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.
