E712 "true-false-comparison" incorrectly raises on array like

[tigerhawkvok]

Consider

import pandas as pd
s = pd.Series([True, True, False, False, None, None])
filter = s != False # [True, True, False, False, True, True]
notAFilter = s is not False # True

or similar operations on array-likes. Here, E712 is very much not equivalent, and in fact, wrong.

This may not be tractable as it requires type analysis.

Thanks! I think this is the same as this open issue: #4560.
