d4a8fc3a87
This patch adds a new BranchOnCount VPInstruction opcode with 2 operands. It first compares its 2 operands (increment of canonical induction and vector trip count), followed by a branch to either the exit block or back to the vector header. It must be the last recipe in the exit block of the topmost vector loop region. This extracts parts from D113224 and was discussed in D113223.
