I want a *single* depfile for *anything* scanned by the `clang-scan-deps` invocation, not one per TU scanned. Also note that the `-MT` is the output of `clang-scan-deps`; in this case, the `.ddi` file that contains P1689 <https://reviews.llvm.org/P1689> content. I think it'd be *very* weird to have `clang-scan-deps -p1689-output=out.ddi -- clang -MF blah.d -MT out.ddi`.
