      PPC: Remove register index/code indirection · f53fda63

      Original commit message:
          Previous to this patch, both the lithium and TurboFan register
          allocators tracked allocated registers by "indices", rather than
          the register codes used elsewhere in the runtime. This patch
          ensures that codes are used everywhere, and in the process cleans
          up a bunch of redundant code and adds more structure to how the
          set of allocatable registers is defined.
      
          Some highlights of changes:
      
          * TurboFan's RegisterConfiguration class moved to V8's top level
            so that it can be shared with Crankshaft.
          * Various "ToAllocationIndex" and related methods removed.
          * Code that can be easily shared between Register classes on
            different platforms is now shared.
          * The list of allocatable registers on each platform is declared
            as a list rather than implicitly via the register index <->
            code mapping.
