This allows the compiler to see and perform basic checks on the call
even in builds with `DXX_WORDS_NEED_ALIGNMENT == 0`.
Also, fix a missing address-of operator in one invocation of
`align_polygon_model_data`.
Reported-by: Brunnis <https://github.com/dxx-rebirth/dxx-rebirth/issues/687> (missing address-of operator)
Fixes: 43e1c841f0
