Subject: Added UltraSparcInstrInfo class to specialize class MachineInstrInfo.
 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.
