[InstCombine] icmp-logical.ll: restore the original intention of the test.

While that fold is clearly not happening [anymore],
we do now have separate test cases for these cases,
so we should be ok to slightly adjust these tests
to not potentially loose test coverage.

As suggested by Hiroshi Yamauchi in
