Relevant changes elsewhere: Added MachineInstrInfo class and moved instruction-related members there. Added several fields to MachineInstrDescriptor (and renamed it from MachineInstrInfo. Latency fields are to support scheduling. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@311 91177308-0d34-0410-b5e6-96231b3b80d8
