@joker-eph I was thinking that maybe we could model `linalg.index` as loading from a specific resource which does not alias the heap, similar to how `TransformMappingResource` and `PayloadIRResource` are used [here](https://github.robot.car/cruise/mla-robocomp-llvm-project/blob/2af58a119ec3697bd1f01e5a1911d6fcc2090421/mlir/include/mlir/Dialect/Transform/IR/TransformInterfaces.h#L1189).  Not sure if this can be easily done though.
