  Log Message:
  -----------
  [AArch64] [FrameLowering] Allow conditional insertion of CFI instruction

Summary:
The insertion of most CFI instructions during AArch64 frame lowering can
be disabled (e.g. using the function attribute `nounwind`).

This patch enables conditional insertion for one more CFI instruction.
