  [InstCombine] Don't preserve context across div

We can't preserve the context across a non-speculatable instruction,
as this might introduce a trap. Alternatively, we could also
insert all the replacement instruction at the use-site, but that
would be a more intrusive change for the sake of this edge case.

Fixes https://github.com/llvm/llvm-project/issues/95547.
