Revert of Avoid excessive GCs in small heaps. (patchset #1 id:1 of https://codereview.chromium.org/1144223002/) Reason for revert: Regressed Sunspider. Original issue's description: > Avoid excessive GCs in small heaps. > > Small heaps and small heap growing factor can lead to excessive GCs in corner cases. > > Consider function F(old_gen_size, factor) that returns the number of bytes that > have to be allocated in the old generation to start incremental marking. > > F(4MB, 1.1) = 4MB (because of kMinimumOldGenerationAllocationLimit) > F(6MB, 1.1) = 2MB (because of kMinimumOldGenerationAllocationLimit) > F(8MB, 1.1) = 800KB > > Funtion F should be monotonic in old_gen_size, but it currently has a minimum > at kMinimumOldGenerationAllocationLimit. > > This CL makes F monotonic. > > BUG= > > Committed: https://crrev.com/22b1da99732b4db0754bf267ec470a2831216fb2 > Cr-Commit-Position: refs/heads/master@{#28549} TBR=hpayer@chromium.org NOPRESUBMIT=true NOTREECHECKS=true NOTRY=true BUG= Review URL: https://codereview.chromium.org/1152533002 Cr-Commit-Position: refs/heads/master@{#28558}
