implement Array-specific #all?, #none?, #one?

Browse source 
Before this patch Array#all? was not implemented in Array class
and alternatively Enumerable#all? was used, while #any? has its
own method entry in Array class.  Similarly, Array#none? and #one?
also lacks its own implementation.
This patch provides Array-specific implementations for above three
methods to enable faster method lookup.

[Fix GH-2041]
