History
Nathan Bossart 3d0b4b1068 Use a non-locking initial test in TAS_SPIN on AArch64. 
Our testing showed that this is helpful at sufficiently high
contention levels and doesn't hurt performance on smaller machines.
The new TAS_SPIN macro for AArch64 is identical to the ones added
for PPC and x86_64 (see commits bc2a050d40 and b03d196be0).
