Summary: - Constant expressions may not be added in strict postorder as the forward instruction scan order. Thus, for a constant express (CE0), if its operand (CE1) is used in an previous instruction, they are not in postorder. However, different from `cloneInstructionWithNewAddressSpace`, `cloneConstantExprWithNewAddressSpace` doesn't bookkeep uninferred instructions for later resolving. That results in failure of inferring constant address. - This patch adds the support to infer constant expression operand recursively, since there won't be loop, if that operand is another constant expression.
