ilist of MachineInstr objects. This allows constant time removal and insertion of MachineInstr instances from anywhere in each MachineBasicBlock. It also allows for constant time splicing of MachineInstrs into or out of MachineBasicBlocks. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@11340 91177308-0d34-0410-b5e6-96231b3b80d8
