test commit: [bd1be8a](https://github.com/llvm/llvm-project/commit/bd1be8a242384d98ef2087f4571b464e01501f5a)
step to reproduce:
```
mlir-opt test.mlir --test-scf-pipelining=no-epilogue-peeling
```
test case:
```
module {
func.func @main() {
%c1 = arith.constant 1 : index
%0 = arith.subi %c1, %c1 : index
scf.for %arg1 = %c1 to %c1 step %0 {
%token = async.execute {
async.yield
}
}
return
}
}
```
Crash backtrace:
```
mlir-opt: /home/workdir/llvm-project/llvm/include/llvm/Support/MathExtras.h:428: T llvm::divideCeilSigned(U, V) [U = long, V = long, T = long]: Assertion `Denominator && "Division by zero"' failed.
