test/unit: optionally verify GC consistency after each test

Browse Source 
Set RUBY_TEST_GC_VERIFY to call GC.verify_internal_consistency after each
test. An integer >= 2 samples once every N tests; any other non-empty value
verifies every test. Useful for pinning down which test corrupts the heap.
