[Mlir-commits] [mlir] [MLIR][XeGPU] Enhance multi-reduction layout propagation rules (PR #186308)

The main addition is that now we try to reuse the consumer's parent sg layout if possible (i.e., the consumer is a simple slice wrapper with the same slice dims as the multi reduction), do I understand this right?

The fractional subgroup size behavior for reductions needs to be defined somewhere. Did I miss a PR that introduces it to XeGPU distribution infra? If yes, could you please link it here?
