Jakob Stoklund Olesen 99c416c9f7 Actually use the MachineOperand field for isRegTiedToDefOperand().
The MachineOperand::TiedTo field was maintained, but not used.

This patch enables it in isRegTiedToDefOperand() and
isRegTiedToUseOperand() which are the actual functions use by the
register allocator.
