[PATCH] D49401: TII: Generalize X86's isSafeToClobberEFLAGs

[Matthias Braun via Phabricator via llvm-commits]

MatzeB added a comment.

Is this different from `MachineBasicBlock::computeRegisterLiveness(TRI, Reg, I, 4) == LQR_Dead`?
The implementations looks the same to me except that this one here has one more case where it checks the successor blocks live in lists...
