> NVPTX/implicit-def.ll - this isn't testing what it intended to test, but I don't know how to do that...could just delete the file?

This test is from 2013 and hasn't had a meaningful change since then.  It's not totally clear to me what it's testing, but it looks like it's checking for a crasher.

I suspect that in the years since then we're a-ok on covering this.  I support deleting it.
