I was going to say "we avoid setting mllvm flags in the Driver" because LLVM
option parsing handles duplicate options as an error conflict, rather than
"last one wins silently", but I found lots of prior art contradicting that
position, so I think you're in the clear:
```
$ git grep mllvm ../clang/lib/Driver/ | wc -l
100
