Actually, it looks like there was something seriously broken locally  
in my tree.  Cleaning llvm-upgrade and rebuilding it seems to have  
cleared up many of the issues, but I still have some failures, e.g.  
in Transforms/SimplifyCFG/2006-12-08-Ptr-ICmp-Branch.ll:

$ ../../../TestRunner.sh 2006-12-08-Ptr-ICmp-Branch.ll
******************** TEST '2006-12-08-Ptr-ICmp-Branch.ll' FAILED!  
llvm-upgrade < 2006-12-08-Ptr-ICmp-Branch.ll | llvm-as | opt - 
simplifycfg | llvm-dis
llvm-as: <stdin>:54,0: Reference to an invalid definition: 'tmp.s' of  
type 'i32'
opt: Standard Input is empty!
llvm-dis: Standard Input is empty!

Sorry for the confusion.
