Mikael Holmen 49af72e55b Use TRI->regsOverlap() in MachineBasicBlock::computeRegisterLiveness
Summary:
For the loop that used MCRegAliasIterator this should be NFC.

For the loop that previously used MCSubRegIterator we should
now detect more cases where the register is actually live out that
we previously missed.
