  Log Message:
  -----------
  [AArch64][Windows] Fix the slot offset of the swift async context register.

This fixes a code gen issue where savings the swift async context
register (x22) accidentally overwrites the saved value of another
callee-saved register, corrupts its value and causes a crash.
