Description:
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.
