I think I benchmarked it manually, and no corruptions were seen, and I
also ran a full test-suite with compiler-rt, but forgot to check if
the calls were actually being made. I now believe that I was either
very lucky, or LLVM generated DIV instructions instead of calling the
function altogether.

Anyway, thanks everyone for the task force! Crisis averted!
