The following getters were moved to the TypedArray/DataView prototype chain with ES2015, and hence need different treatment now: - DataView.prototype.buffer - DataView.prototype.byteLength - DataView.prototype.byteOffset - TypedArray.prototype.buffer - TypedArray.prototype.byteLength - TypedArray.prototype.byteOffset - TypedArray.prototype.length Instead of having special magic on the LoadIC in the IC system and the optimizing compilers, as we used to do before (and which we got rid of already), we just treat those as normal accessors and make them recognizable via the BuiltinFunctionId mechanism. This allows us to remove some of the additional magic from the IC subsystem, and just extend the BuiltinFunctionId mechanism in Crankshaft slightly to cover these cases too (TurboFan doesn't yet support accessors, but that will be fixed soonish anyways). This addresses most of the 15-20% regression we saw on the Octane GameBoy emulator benchmark.
