  Log Message:
  -----------
  AAArch64: disable asynchronous unwind by default for MachO.

AArch64 MachO has a compact unwind format where most functions' unwind info can
be represented in just 4 bytes. But this cannot represent any asynchronous CFI
function, so it's essentially disabled when that's used. This is a large
code-size hit that we'd rather not take unless explicitly requested.
