  [BOLT] Ensure remember and restore CFIs are in the same list (#144348)

In `addCFIInstruction`, we split the CFI information
between `CFIInstrMapType CIEFrameInstructions` and `CFIInstrMapType
FrameInstructions`. In some cases we can end up with the remember CFI in
`CIEFrameInstructions` and the restore CFI in `FrameInstructions`. This
patch adds a check to make sure we do not split remember and restore
states and fixes https://github.com/llvm/llvm-project/issues/133501.
