  -----------
  [InferAddressSpaces] Insert fixup casts before cloned user during rewriting phase (#226987)

After reworking `operandWithNewAddressSpaceOrCreatePoison` in #225161 in
order to handle joins of different address spaces in the lattice to a
more specific address space, ensure that casts created during the fix-up
phase of poison uses are placed before the cloned user, as the latter
has already been inserted above the original instruction in
`cloneValueWithNewAddressSpace`.
