Zero filled array creation (v4)

Revision 4 of this benchmark created on

Description

Creating an array filled with zeros. Which is the fastest method? These methods are useful for arrays filled with a single element, except for the typed array conversion which works only with zeros. Only the first two methods are useful with incremental values or callbacks.
