bb12903120 type 'Udata' refers directly to structure inside the union (union
used only for aligning purposes now)

ca41b43f53 type 'TString' refers directly to the structure inside the union

5a9cc57a5e change in GCObject: instead of being a union, it is now a structure
with the common header of all collectable objects; union is used
only for conversions. (Goal is to be able to check that the cast
'obj2gco' can have a check to ensure that object being converted
is really a collectable object.). This is the first step in the
change.
