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. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@171246 91177308-0d34-0410-b5e6-96231b3b80d8

reapply r121100 with a tweak to constant fold ConstExprs with TargetData (if available) as we go so that we get simple constantexprs not insane ones. This fixes the failure of clang/test/CodeGenCXX/virtual-base-ctor.cpp that the previous iteration of this patch had. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@121111 91177308-0d34-0410-b5e6-96231b3b80d8
