URL: https://github.com/apache/tvm/pull/13808
This PR tries to fix the crash of the pass `RemoveNoOp` when the condition
of IfThenElseNode can be statically determined. For example:
```python
@L.prim_func
def remove_no_op():
if True:
L.evaluate(0)
else:
L.evaluate(0)
```
This case will cause `Segment fault` error because `RemoveNoOp` don't cover
the case the return of `Parent::VisitStmt_` is not a `IfThenElseNode`, which
will result in the `stmt.as<IfThenElseNode>()` being `null`.
