[fpc-pascal] Generic type parameter variable initialization

I am sorry, I wasn't aware of that. But by means of testing I found
that Finalize() works correctly for Variants in Lazarus as well. I
don't know about the internals much but I suppose the place to look in
FPC is procedure fpc_finalize() in objpas.inc which does handle
tkVariant as well.

I think it is, it works in my Delphi XE exactly the way it does in
Lazarus. It is just not defined in Delphi's RTL. I meant it as a temp
solution until you implement Default() or something equivalent.

Anyway, let me not waste any more of your time. :)

Regards.
