[PATCH] D28489: [CodeGen] Generalize MacroFusion for any instructions pair

Yep, this could all be done in the target. SDep::Cluster is effectively a scheduler API for the subtarget to use as it wishes.

On the other hand, that just pushes the problem to the target code, and this is proposed for AArch64.
