Eli Friedman 2adc5b6a17 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. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@127299 91177308-0d34-0410-b5e6-96231b3b80d8		2011-03-09 00:48:33 +00:00
