machenbach 301151545e Revert of Force full GCwhenever CollectAllGarbage is meant to trigger a full GC. (patchset #4 id:60001 of https://codereview.chromium.org/1082973003/)
Reason for revert:
[Sheriff] Breaks http://build.chromium.org/p/client.v8/builders/V8%20Linux%20-%20nosnap%20-%20debug/builds/3348 and maybe leads to timeouts/crashes on layout test bots:
http://build.chromium.org/p/client.v8/builders/V8-Blink%20Linux%2064/builds/3002

Original issue's description:
> Force full GC whenever CollectAllGarbage is meant to trigger a full GC.
>
> Add a finalize incremental marking mode for CollectAllGarbage to finalize incremental marking when incremental marking is in progress, but we want a full gc at a given CollectAllGarbage call site.
>
> Default mode for CollectAllGarbage is finalize incremental marking and perform a full GC.
