  Log Message:
  -----------
  [llvm][AArch64] Autoupgrade function attributes from Module attributes. (#80640)

`sign-return-address` and similar module attributes should be propagated
to the function level before modules got merged because module flags may
contradict and this information is not recoverable.
Generated code will match with the normal linking flow.
