Backport of d800a65, 7a88ff3, and a715957 from V8 upstream to v4.x

These commits would not land cleanly on v4.x and needed to be manually reproduced. Due to the commits needing to be manually recreated I would appreciate a slightly more thorough review of this PR.

Conflicts:

  • 6403bb2:
    • Does not include changes to SLOW_DCHECK
  • d91c6ae:
    • Does not include changes to src/heap/scavenger.cc
    • These changes would be reverted in 477fb96 so they can be considered a no-op
  • 477fb96:
    • Does not include changes to src/heap/scavenger.cc
    • this negates the changes not included in d91c6ae

If this is 3 commits, should the patch level be bumped 3 times?

IMO it is not necessary to bump the patch level on each commit – although an argument could be made that the commits be squashed. Upstream does squash when doing back-merges. In this case, each of the commit ended being slightly different from the upstream version, but as long as that is documented in the PR here, it might be okay to squash? I don't have strong feelings on this however.
