Reverts llvm/llvm-project#135429 due buildbot breakage:

Based on the ASan output, I think after the replaceOp on line 775, it's
no longer valid to do getSize() on sliceOp:
```
775 rewriter.replaceOp(sliceOp, newSliceOp.getResult());
776
777 // Remove const_shape size op when it no longer has use point.
778 Operation *sizeConstShape = sliceOp.getSize().getDefiningOp();
```
