Herald added a project: LLVM.

This reverts the AMDGPU DAG mutation implemented in D72487 <https://reviews.llvm.org/D72487> and gives
a more general way of adjusting BUNDLE operand latency.

It also replaces FixBundleLatencyMutation with adjustSchedDependency
callback in the AMDGPU, fixing not only successor latencies but
predecessors' as well.
