Subject: [PATCH] FileCheck-ize test and make sure more things don't happen.
Attribute 'nodebug' means no llvm.dbg.* intrinsics, no !dbg
annotations, and no DISubprogram for the function.
Differential Revision: http://reviews.llvm.org/D10747
git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@240747 91177308-0d34-0410-b5e6-96231b3b80d8
