  -----------
  [AArch64] Regenerate and add more tests for i128 atomics.

Generating these tests unfortunately means a lot of junk, but it's hard
to write/update these tests by hand.

Added tests focus on atomic orderings for cmpxchg.

Actually writing out these tests showed some potentially dubious
results; we should probably consider using casp for 128-bit atomic
load/store/rmw.
