Subject: Rename SSARegMap -> MachineRegisterInfo in keeping with the idea that
 "machine" classes are used to represent the current state of the code being
 compiled.  Given this expanded name, we can start moving other stuff into it.
  For now, move the UsedPhysRegs and LiveIn/LoveOuts vectors from
 MachineFunction into it.

Update all the clients to match.

This also reduces some needless #includes, such as MachineModuleInfo
from MachineFunction.
