+    Error in removing dead code:
+    In an if condition is a loop.  We optimized the if condition to Jmp/Bad,
+    the loop now is unreachable.  It should be removed by gigo or the like.
+    It remains in the representation as all blocks in the loop have a
+    valid predecessor, i.e., walking from End we find a true loop.  We need
+    a pass walking and marking starting at the Start node to remove this loop.
+    Currently scc causes an segmetation fault for this situation.

+  + Goetz 10.6.04
+    Error in irscc:  If we have an unreachable loop, or a loop
+    resulting from an exiting endless recursion, irscc finds
+    no tail ==> issues an assertion.

+  * Goetz 10.6.04
+    Error in interprocedural view:  Endless recursions are lost.
