[AArch64] Async unwind - Adjust unwind info in AArch64LoadStoreOptimizer
The AArch64LoadStoreOptimnizer pass may merge a register
increment/decrement with a following memory operation. In doing so, it
may break CFI by moving a stack pointer adjustment past the CFI
instruction that described *that* adjustment.
This patch fixes this issue by moving said CFI instruction after the
merged instruction, where the SP increment/decrement actually takes
place.
