[PATCH] D87071: [Scheduling] Add a mutation to schedule GOT indirect instructions close to each other for linker optimization

[Qing Shan Zhang via Phabricator via llvm-commits]

steven.zhang added a comment.

Simplify the logic and add tests. We still have cases that Peephole cannot handle due to missing the dependency information. But we don't want to handle it inside the scheduler as that is not right.
