  Changed paths:

    M llvm/test/CodeGen/AArch64/sign-return-address.ll

  Log Message:
  -----------
  AArch64: Don't use RETA[AB] when ShadowCallStack is enabled.

When returning from a function with both SCS and PAC-RET enabled, we need to
authenticate the return address from the stack and then load from the SCS,
but this was happening in the reverse order when RETA[AB] were being used.
Fix it by disabling the use of RETA[AB] when SCS is enabled.

Fixes pr58072.
