gas: .sizeof.() / .startof.() creating redundant symbol table entries

Given that these are undocumented features I do not think that we need to
worry about efficiency.  I would say go with the simplest solution that
comes to mind.  Personally I would go with a small array which can be
realloced if necessary.  But that is just me.

It might be worth adding a little bit of documentation too, just to be
kind to potential users.

Cheers
