  Fix PR46880: Fail CHECK-NOT with undefined variable

Currently a CHECK-NOT directive succeeds whenever the corresponding
match fails. However match can fail due to an error rather than a lack
of match, for instance if a variable is undefined. This commit makes match
error a failure for CHECK-NOT.
