This required plumbing a TargetRegisterInfo through computeRegisterProperties and into findRepresentativeClass which uses it for register class iteration. This required passing a subtarget into a few target specific initializations of TargetLowering. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@230583 91177308-0d34-0410-b5e6-96231b3b80d8
