[X86] vector-reduce-and-cmp.ll - and reductions should compare against -1 not 0 for allof style comparisons

Fix tests so we actually test what was intended to complement vector-reduce-or-cmp.ll - this was a copy+paste typo from the vector-reduce-or-cmp.ll file (where we should compare against 0) - comparing reduce_and against 0 doesn't tell us much (other than no common set bits).
