4cd16f2a - [BOLT][AArch64] Add more heuristics on epilogue determination (#167077)

[BOLT][AArch64] Add more heuristics on epilogue determination (#167077) Add more heuristics to check if a basic block is an AArch64 epilogue. We assume instructions that load from stack or adjust stack pointer as valid epilogue code sequence if and only if they immediately precede the branch instruction that ends the basic block.
