bors e1842b0cac Auto merge of #5583 - ebroto:reversed_empty_ranges, r=yaahc,flip1995 
Reversed empty ranges

This lint checks range expressions with inverted limits which result in empty ranges. This includes also the ranges used to index slices.

The lint reverse_range_loop was covering iteration of reversed ranges in a for loop, which is a subset of what this new lint covers, so it has been removed. I'm not sure if that's the best choice. It would be doable to check in the new lint that we are not in the arguments of a for loop; I went for removing it because the logic was too similar to keep them separated.

changelog: Added reversed_empty_ranges lint that checks for ranges where the limits have been inverted, resulting in empty ranges. Removed reverse_range_loop which was covering a subset of the new lint.

Closes #4192
Closes #96
