[heap] Flush conservatively for GCs within a single second

The minimum interval for time-based flushing increases is 1s. Multiple
GCs within 1s could thus aggressively advance the time that is used to
check whether SFIs have not been used recently.

The rest of the system already works conservatively, so adjust this
case to also conservatively handle the case by suming up time deltas
of consecutive GCs that fell below the 1s threshold.

Getting the Code

Checkout depot tools, and run

    fetch v8

This will checkout V8 into the directory v8 and fetch all of its dependencies. To stay up to date, run

    git pull origin
    gclient sync

For fetching all branches, add the following into your remote configuration in .git/config:

    fetch = +refs/branch-heads/*:refs/remotes/branch-heads/*
