PPC: More simplification and unification of frame handling

PPC: More simplification and unification of frame handling

Port 55071954bcd65be6782388624b986e9751899377

Original commit message:
    Frame slots indexes numbers are used more consistently for
    computation in both TurboFan and Crankshaft. Specifically,
    Crankshaft now uses frame slot indexes in LChunk, removing
    the need for some special-case maths when building the
    deoptimization translation table.
