  Log Message:
  -----------
  Reland "[NVVM] Upgrade nvvm.ptr.* intrinics to addrspace cast" (#110262)

Remove the following intrinsics which can be trivially replaced with an
`addrspacecast`

  * llvm.nvvm.ptr.gen.to.global
  * llvm.nvvm.ptr.gen.to.shared
  * llvm.nvvm.ptr.gen.to.constant
  * llvm.nvvm.ptr.gen.to.local
  * llvm.nvvm.ptr.global.to.gen
  * llvm.nvvm.ptr.shared.to.gen
  * llvm.nvvm.ptr.constant.to.gen
  * llvm.nvvm.ptr.local.to.gen

Also, cleanup the NVPTX lowering of `addrspacecast` making it more
concise.

This was reverted to avoid conflicts while reverting #107655. Re-landing
unchanged.
