I'd be totally happy putting such tests under clang.  This whole
discussion was spurred by D68230 where some noted that previous
discussion had determined we didn't want source-to-asm tests in clang
and the test update script explicitly forbade it.

If we're saying we want to reverse that decision, I'm very glad!
