Eli Friedman d1e9ff0d6c PR9420; an instruction before an unreachable is guaranteed not to have any ... reachable uses, but there still might be uses in dead blocks. Use the standard solution of replacing all the uses with undef. This is a rare case because it's very sensitive to phase ordering in SimplifyCFG. llvm-svn: 127299		2011-03-09 00:48:33 +00:00
