…to continue tile + fuse. (llvm#107882) Current implementation of `scf::tileConsumerAndFuseProducerUsingSCF` looks at operands of tiled/tiled+fused operations to see if they are produced by `extract_slice` operations to populate the worklist used to continue fusion. This implicit assumption does not always work. Instead make the implementations of `getTiledImplementation` return the slices to use to continue fusion. This is a breaking change - To continue to get the same behavior of `scf::tileConsumerAndFuseProducerUsingSCF`, change all out-of-tree implementation of `TilingInterface::getTiledImplementation` to return the slices to continue fusion on. All in-tree implementations have been adapted to this. - This change touches parts that required a simplification to the `ControlFn` in `scf::SCFTileAndFuseOptions`. It now returns a `std::optional<scf::SCFTileAndFuseOptions::ControlFnResult>` object that should be `std::nullopt` if fusion is not to be performed.
