Move copyRegToReg from MRegisterInfo to TargetInstrInfo. This is part of the

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.

Remove isReg, isImm, and isMBB, and change all their users to use
...
isRegister, isImmediate, and isMachineBasicBlock, which are equivalent,
and more popular.

Add a MachineFunction pass, which runs post register allocation, that turns subreg insert/extract instruction into register copies. This ensures correct code gen if the coalescer isn't able to remove all subreg instructions.
