[PATCH] D12371: Expose hasLiveCondCodeDef as a member function of the X86InstrInfo class. NFC

[Kevin B. Smith via llvm-commits]

This takes the existing static function hasLiveCondCodeDef and makes it a member function of the X86InstrInfo class.  This is a useful utility function that an upcoming change would like to use. NFC.
