subtarget CPU descriptions and support new features of MachineScheduler. MachineModel has three categories of data: 1) Basic properties for coarse grained instruction cost model. 2) Scheduler Read/Write resources for simple per-opcode and operand cost model (TBD). 3) Instruction itineraties for detailed per-cycle reservation tables. These will all live side-by-side. Any subtarget can use any combination of them. Instruction itineraries will not change in the near term. In the long run, I expect them to only be relevant for in-order VLIW machines that have complex contraints and require a precise scheduling/bundling model. Once itineraries are only actively used by VLIW-ish targets, they could be replaced by something more appropriate for those targets. This tablegen backend rewrite sets things up for introducing MachineModel type #2: per opcode/operand cost model. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@159891 91177308-0d34-0410-b5e6-96231b3b80d8
