First chunk of MachineInstr bundle support.
1. Added opcode BUNDLE 2. Taught MachineInstr class to deal with bundled MIs 3. Changed MachineBasicBlock iterator to skip over bundled MIs; added an iterator to walk all the MIs 4. Taught MachineBasicBlock methods about bundled MIs git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@145975 91177308-0d34-0410-b5e6-96231b3b80d8
