Rule proposal: `no-unnecessary-length-check-before-some-every`

I havn’t think through the details, but cases:

Fail

if (array.length === 0 || array.every(Boolean)) {}

if (array.length !== 0 && array.some(Boolean)) {}

Pass

if (array.every(Boolean)) {}

if (array.some(Boolean)) {}

if (array.length !== 0 && array.every(Boolean)) {}

if (array.length === 0 || array.some(Boolean)) {}

To ensure array is not empty and elements passes test.

How about Array#map or such check before a loop?
