reg_begin/reg_end - Provide iteration support to walk over all definitions and uses of a register within the MachineFunction that corresponds to this MachineRegisterInfo object.
defusechain_iterator - This class provides iterator support for machine operands in the function that use or define a specific register.
If ReturnUses is true it returns uses of registers, if ReturnDefs is true it returns defs. If neither are true then you are silly and it always returns end(). If SkipDebug is true it skips uses marked Debug when incrementing.
