Subject: Avoid creating verification_results_ unnecessarily

For compiler filters that don't quicken or compile, avoid creating
the verification results. This avoids creating some arrays that
were using a few MB of RAM in some cases.

For a large app verify compile:
Maximum resident set size (kbytes): 258948 -> 254300

Bug: 63467744
Test: test-art-host
