The script mangled both virtual-functions-base-pointer-call.ll and virtual-functions-derived-pointer-call.ll pretty badly, deleting the run line and most of the block comment. Replaced the bitcast with and addrspacecast in 2002-07-17-CastRef.ll, based on the apparent intent of the test. For 2003-07-01-SelfReference.ll, the script produced "call ptr () @getfunc" which surprisingly parses as valid.
