Change these tests to feed the assembly files to opt directly, instead of using llvm-as, now that opt supports this. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@81226 91177308-0d34-0410-b5e6-96231b3b80d8 2009-09-08 16:50:01 +00:00			`; RUN: opt %s -instcombine \| llvm-dis \| grep {ret i1 true}`
