[AArch64][WinCFI] Do not pair callee-save instructions in LoadStoreOptimizer

instructions from the prologue/epilogue if the CFI information has encoded the
operations as separate instructions. This would otherwise lead to a mismatch
of the actual prologue size from the size as recorded in the Windows CFI.
