Instead, just create one, and make sure everything that needs it can access it. Previously most of the SelectionDAGISel subclasses all had their own TargetLowering object, which was redundant with the TargetLowering object in the TargetMachine subclasses, except on Sparc, where SparcTargetMachine didn't have a TargetLowering object. Change Sparc to work more like the other targets here. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@57016 91177308-0d34-0410-b5e6-96231b3b80d8
