[InstCombine] Don't fold select(C, Z, binop(select(C, X, Y), W)) -> select(C, Z,...

[InstCombine] Don't fold select(C, Z, binop(select(C, X, Y), W)) -> select(C, Z, binop(Y, W)) if the binop is rem or div.

The select may have been preventing a division by zero or INT_MIN/-1 so removing it might not be safe.

Fixes PR36362.
