[Mlir-commits] [mlir] [mlir][Transform] Fix crash in SequenceOp::getEffects when body region is empty (PR #185063)

What's the guideline here? Is `getEffects` (or interface methods in general) allowed to crash if the op is invalid?

Is this actually a problem of `getPotentialTopLevelEffects` or `TestVisitors.cpp`?
