This fixes a memory leak in the CPU profiler: https://bugs.chromium.org/p/v8/issues/detail?id=6623

This affects master, 9.x and 8.x. master should pick this up through a regular V8 update (if the merge gets approved). This PR is for 9.x. This should cherry-pick to 8.x easily except for the version bump, which will need to be migrated to v8-version.h.

Original commit message:

[cpu-profiler] Clear code entries when no observers are present.

Performed manual testing as well by making 20 CPU profile recordings of
loading http://meduza.io page. Without the patch the page renderer memory size
grows beyond 300MB. With the patch it remains below 200MB.

Looking at the V8 CI, the same test is failing in all four environments. I reran the V8-CI against v9.x: https://ci.nodejs.org/job/node-test-commit-v8-linux/1109/. The same test is failing there as well. Running the V8 tests locally against the V8 branch-heads/6.2 branch with and without the patch passes the tests. This must be an issue in the V8-CI or a regression in a floating patch. /cc @mhdawson any ideas?

I think this PR is good to go for 8.x and 9.x. /cc @gibfahn

Landed in 2f919ed

Failing test was fixed in #17383
fips failure is unrelated (fix for flake also landed)

@gibfahn I can reproduce the issue. I am investigating.

ofrobots added a commit to ofrobots/node that referenced this pull request Dec 13, 2017
@ofrobots
deps: V8: backport 14ac02c from upstream
59c3996 
This is the V8 6.1 specific backport for Node 8.x.

Original commit message:
  [cpu-profiler] Clear code entries when no observers are present.

  Performed manual testing as well by making 20 CPU profile recordings of
  loading http://meduza.io page. Without the patch the page renderer memory size
  grows beyond 300MB. With the patch it remains below 200MB.

Additional fixup was needed for 8.x (V8 6.1). I have opened a separate 8.x specific PR at #17659.

Attaching dont-land-on-8.x label here.
