Similarly, the following example can also trigger a crash.
```python
import tvm
from tvm import tir
var = tir.Var('var', 'int32')
false_value = tir.Cast('int32', tir.acosh(tir.Cast('float32', var)))
value = tir.Select(var > 0, tir.const(0), false_value)
let_stmt = tir.LetStmt(var, value, tir.Evaluate(var))
f = tir.PrimFunc({}, let_stmt)
tvm.build(f)
```
Different from the last example, this bug crashes in `PrimExpr
RewriteSimplifier::Impl::VisitExpr_(const LTNode* op)`
