Original commit message:

    [turbofan] Boost performance of Array.prototype.shift by 4x.

    For small arrays, it's way faster to just move the elements instead of
    doing the fairly complex and heavy-weight left-trimming. Crankshaft has
    had this optimization for small arrays already; this CL more or less
    ports this functionality to TurboFan, which yields a 4x speed-up when
    using shift on small arrays (with up to 16 elements).

    This should recover some of the regressions reported in the Node.js issues

      https://github.com/nodejs/node/issues/12657

    and discovered for the syncthrough module using

      https://github.com/mcollina/syncthrough/blob/master/benchmarks/basic.js

    as benchmark.
