ulan d09e026a9e Revert of [heap] Simplify heuristics for incremental step size. (patchset #5 id:180001 of https://codereview.chromium.org/2290333002/ ) 
Reason for revert:
Regressed GC times in v8.infinite_scroll_tbmv2 benchmarks.

Original issue's description:
> [heap] Simplify heuristics for incremental step size.
>
> This patch removes the code for speeding up marking.
>
> Now the step size depends on allocated bytes and
> invoked write barriers.
>
> We also ensure that the step size is large enough to
> justify the overhead of interrupting the generated code.
