Heads up: MCRegisterInfo register list functions going away

I am going to remove these functions from MCRegisterInfo:

  getSubRegisters()
  getSuperRegisters()
  getOverlaps()
  getAliasSet()

They have been replaced with iterator classes, also defined in MCRegisterInfo.h:

  MCSubRegIterator
  MCSuperRegIterator
  MCRegAliasIterator

The tree has lots of examples of how to use all three.
