Details

According to the latest results arrow-declare test is 439x slower in Firefox 43 than es5 implementation. I understand that micro-benchmarks are sub-optimal, but it seems that there's a regression between Fx40 and Fx43 worth investigating.
Blocks: six-speed
Updated tests still show 338x slower in Firefox 44.
Depends on: 1355155
Depends on: 1405457
The performance is now identical. As usual with six-speed we can just optimize most of the code away and we aren't actually testing arrow function allocation anymore.
