[PATCH] D29448: [RegAlloc] Don’t freeze reserved registers again if it is not necessary

Hi Volkan,

I think LiveVariables is not used anymore and the MachineVerifier could certainly be adapted.

Could you check how DeadMachineInstructionElim uses that information and how we can live without the reserved set to be frozen?

Cheers,
-Quentin
