GlobalISel: implement legalization pass, with just one transformation. This adds the actual MachineLegalizeHelper to do the work and a trivial pass wrapper that legalizes all instructions in a MachineFunction. Currently the only transformation supported is splitting up a vector G_ADD into one acting on smaller vectors. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@276461 91177308-0d34-0410-b5e6-96231b3b80d8
