[PATCH] D24215: [RFC] AMDGPU: Add MachineInstr::Initiator and ::Terminator flags

[Matt Arsenault via llvm-commits]

arsenm added a comment.

I've been moving more in the direction of not considering mask branches as branches at all, and their own separate concept. My patch adds a handful of terminator instruction aliases that are replaced after register allocation with the regular instructions, since it's only used to get correct spill code placement.
