[PATCH] D69998: [MacroFusion] Create the missing artificial edges if there are more than 2 SU fused.

[Qing Shan Zhang via Phabricator via llvm-commits]

steven.zhang added a comment.

I will split this patch into two in response with Jinsong's comments.

1. Fix the missing edges.
2. Extend the interface to allow the target to specify the max fuse SU number.
