[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. Differential Revision: https://reviews.llvm.org/D43276 llvm-svn: 325148
