This simple patch fixes a wrong indent and adds a _final component to 
the virtual tables generated for intrinsic types.

This patch not only prepares the trunk for finalization support, it also 
avoids ABI issues which a later addition would cause. (For intrinsic 
types, changing the .mod version number will not reliable force a 
recompilation.)

Build on x86-64-gnu-linux.
OK for the trunk?
