The crash comes from mismatch between load count in epilogue and seh instruction count.
Still because of the pass AArch64LoadStoreOpt. It remove some load in the epilogue but haven't remove the corresponding seh instruction.
This patch don't optimize the load in the epilogue to fix the issue.

Fix: #58516
