The scope of `var` is per-function, requiring a transformation for closures inside loops when capturing loop variables. This PR turns off the transformation. This PR should go after #6102

I wonder how much it'll affect performance. But probably it won't be a big difference. |

@DZakh did you see this: #856 (comment) ? |

@cristianoc Could you rebase this? Now that 11.1 is out and development focus is shifting to v12, it would be great to get this merged. |

Fixes #856
Need to check that no cases are missed where this could introduce regressions even if the tests appear to be passing
This will generate a huge amount of noise in the diff w.r.t. other versions of the compiler. It might not be ideal to have this change in an initial version of compiler v11 if other changes are important as they would get lost in the noise
Note that the transformation creating problems in Fix issue with generating async functions inside loops. #6479 can be removed
