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.
