Gareth Ellis 443c2d5442 buffer: changing let in for loops back to var 
Using let in for loops showed a regression in 4.4.0. @ofrobots
suggested that we avoid using let in for loops until TurboFan becomes
the default optimiser.

The regression that was detected was when looking at how long it took
to create a new buffer from an array of data.

When using `for (let i=0; i<length; i++) ` we saw the operation take
almost 40% longer compared to `var i=0`.
