Introducing the LLVM greedy register allocator. This change aims to introduce the separation of the RegisterAllocator model, using the initial prototype for RegisterAllocatorGreedy as proof of concept. Summary: - new flag, turbo-greedy-regalloc, enabling the new allocator. Default false. - separated RegisterAllocator into a base type and two derived, RegisterAllocatorLinear (the one currently used in TurboFan) and RegisterAllocatorGreedy (the new one). - initial, untested impementation for the greedy allocator.
