Tests: rewrite 'opt ... %s' to 'opt ... < %s' so that opt does not emit a ModuleID This is done to avoid odd test failures, like the one fixed in r171243. My previous regex was not good enough to find these. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@171343 91177308-0d34-0410-b5e6-96231b3b80d8 2013-01-01 13:57:25 +00:00			`; RUN: opt -simplifycfg -disable-output < %s`
