dg-cmp-results: display NA->FAIL & NA->UNRESOLVED by default

Currently, dg-cmp-results will not print anything for a test that was
not run before, even if it is a FAIL or UNRESOLVED now. This means that
when contributing a code change together with a testcase in the same
commit one must run dg-cmp-results twice: once to check for regression
on a full testsuite run and once against the new testcase with -v -v.
This also prevents using dg-cmp-results on sum files generated with
test_summary since these would not contain PASS.

This patch changes dg-cmp-results to print NA->FAIL and NA->UNRESOLVED
changes by default.
