Fix a number of issues w.r.t. emission of global for functions and
aliases.
- Attributes specific to a definition are only set when the
definition is seen.
- Alias generation is delayed until the end of the module; necessary
since the alias may reference forward.
- Fixes: PR2743, <rdr://6140807&6094512>
- Improves: <rdr://6095112> (added XFAIL)
Also, print module on verification failures.
