[InstCombine] add test for limitation of knownbits with overshift; NFC

The tests above this were added for D30781 and used to provide
coverage for a limit of knownbits, but improvements in other
transforms killed that intended purpose. This was noted because
another proposed improvement in D117110 will further reduce
those tests.
