  AMDGPU: Fix mishandling of search for constantexpr addrspacecasts

This was assuming that the top level constant expression was an
addrspacecast. The first encountered expression may not be pointer typed,
and may not be the addrspacecast. We need to distinguish the types of
addrspacecasts unlike the previous queue ptr search, so do that.

Fixes #120256
