This is a precursor to generalizing the `tileUsingSCF` to handle
`ReductionTilingStrategy::PartialOuterParallel` strategy. This change
itself is generalizing/refactoring the current implementation that
supports only `ReductionTilingStrategy::PartialOuterReduction`.
Changes in this PR
- Move the `ReductionTilingStrategy` enum out of
`scf::SCFTilingOptions` and make them visible to `TilingInterface`.
- `PartialTilingInterface` changes
- Pass the `tilingStrategy` used for partial reduction to
`tileToPartialReduction`.
- Pass the reduction dimension along as `const
llvm::SetVector<unsigned> &`.
- Allow `scf::SCFTilingOptions` to set the reduction dimensions that
are to be tiled.
- Change `structured.tiled_reduction_using_for` to allow specification
of the reduction dimensions to be partially tiled.
