With the pretenuring changes enabled, the reddit.com pageload test shows a significant number of minor GCs are triggered by the slots storebuffer filling up. This is different to the case where it's disabled where most minor GCs are triggered by the nursery being full.
The whole cell buffer has a maximum size of 128KB but the other buffers have a smaller limit of 48KB.
Increasing the limit to 128KB all around seems to fix the reddit regression on perfherder so let's try that. Note that this is threshold for triggering minor GC, not a fixed sizes that these buffers will occupy.
