Sander de Smalen f7c0c16f0f [AArch64][WinCFI] Do not pair callee-save instructions in LoadStoreOptimizer
Prevent the LoadStoreOptimizer from pairing any load/store instructions with
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.
