as-name: document that identifiers are OK for address spaces

A previous series allowed to used an indentifier to denotate an
address space but this wasn't documented.

Document it now in the manpage.

 Warn about code which mixes pointers to different address spaces.

 override this warning, such as for functions which convert pointers between
