Change tests from "opt %s" to "opt < %s" so that opt doesn't see the input filename so that opt doesn't print the input filename in the output so that grep lines in the tests don't unintentionally match strings in the input filename. llvm-svn: 81537 2009-09-12 02:01:28 +08:00			`; RUN: opt < %s -tailcallelim -S \| grep call`
