For PR1319: Upgrade to use new Tcl exec based test harness. This exposes 3 bugs that were previously not being reported: test/Transforms/GlobalDCE/2002-08-17-FunctionDGE.ll test/Transforms/GlobalOpt/memset.ll test/Transforms/IndVarsSimplify/exit_value_tests.llx llvm-svn: 36065 2007-04-15 17:21:47 +08:00			`; RUN: llvm-upgrade < %s \| llvm-as \| opt -simplifycfg \| llvm-dis \| \`
