Are you sure you don't want it to be recursive?  I can take a global
variable, bitcast it, do a GEP 0 on that, bitcast the result, etc.
The final result will be equivalent to a single bitcast of the original
global.  So shouldn't this code handle it?  Of course if the optimizers
are run then they would simplify such a silly example.  But it seems
wrong to me to assume that the IR has been optimized...

Best wishes,

Duncan.
