Patch for the vla-branch to fix unallocated variables

Hello Jan,

I've encountered a bug in the vla-branch. A patch is attached. The
problem is that when the bounds of an array are determined, the check if
the type is allocated at all is incorrect. 

The 'TYPE_NOT_ALLOCATED' of 'type' is checked. But in the case that
type_not_allocated is a dwarf-block expression, the result is only set
to new_type.

(this results in an invalid memory access)

Regards,

Joost van der Sluis
