[AArch64] Preserve register flags when promoting a load from store.
Summary:
This patch updates promoteLoadFromStore to use the store MachineOperand as the
source operand of the of the new instruction instead of creating a new
register MachineOperand. This way, the existing register flags are
preserved.
This fixes PR33468 (https://bugs.llvm.org/show_bug.cgi?id=33468).
