  [InferAddressSpaces] Extend undef pointer operand support to phi inst (#159548)

Previously undef pointer operand is only supported for select inst,
where undef in generic AS behaves like `take the other side`.

This PR extends the support to other instructions, e.g. phi inst. Defer
joining and inferring constant pointer operand until all other operand
AS states considered.
