Nikita Popov 4d2ae88d16 [InstCombine] Fix invalid scalarization of div ...

If the binop is not speculatable, and the extract index is out of
range, then scalarizing will perform the operation on a poison
operand, resulting in immediate UB, instead of the previous
poison result.

Fixes https://github.com/llvm/llvm-project/issues/97053.
