  allow retain to be specified for unsafeTensorFromTH
  Deduplicate THPUtils_checkLong/THPUtils_unpackLong (pytorch#2218)
  fix osx build errors related to long/int64_t
  Note [Undefined-dim versus 0-dim]

I often create this unit test in my local branch to play around using
manually modified generated code. Giving it a permanent place as it may
be useful for anyone working on code generation.

Cherry-pick of upstream pytorch#154680.
