[GC] Change behavior when reaching external allocation limit With the recent changes to the incremental marking API we can now kick off incremental marking while respecting callback flags. Performance neutral for smoothness.image_decoding_cases on N9 (read: does not crash) as long as we synchronously process phantom callbacks (kGCCallbackFlagForced). OORT single run: "marksweep": { "count": 5, "pause_min": 7.5, "pause_max": 158.8, "pause_avg": 97.52000000000001, "pause_gt_10ms": 4 } --- vs --- "marksweep": { "count": 5, "pause_min": 16.2, "pause_max": 22.1, "pause_avg": 19.32, "pause_gt_10ms": 5 } The number of actual full GCs varies. The improvement manifests in reduced maximum and average pauses. BUG=chromium:515795 LOG=N Review URL: https://codereview.chromium.org/1271253002 Cr-Commit-Position: refs/heads/master@{#30028}
