History
Michael Liao dbb747a8e2 [InferAddressSpaces] Enhance the handling of cosntexpr. 
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.
