Optimize Enum.fetch/2 for maps, negative indexes, out of bound indexes, empty enumerables, and enumerables with only one element.

This function has been highly-optimized, through thorough benchmarking.

There were serious issues when dealing with big lists and maps when an out of bound or a negative index was given. Ex. fetching an out-of-bound index in a 1,000-element map, was reduced to 0.18% of the original item. Or same case with a 1,000-element list time was reduced to a 10,5%.

• Enumerables are no longer reversed when dealing with negative indexes.
