Oops. Missed lint. I guess clang-format doesn't catch this sort of stuff.

The transform doesn't touch comments so they make through to the output file exactly as they go in. This includes CHECK: statements. Therefore when FileCheck runs on the output, every test passes because it matches against the CHECK: comment and not the actual code. The grep just strips out all the FileCheck directives.
