      [wasm] Move the wasm fuzzer corpus to a different directory · 1f629aac
      Andreas Haas authored 
      The current test/fuzzer/wasm directory is used for two things:
1) as the corpus directory for clusterfuzz
2) to test in v8 that the fuzzer runs correctly.

With the newly added files from the wasm spec tests this directory grew
quite big and adds unnecessary load on the trybots. Therefore I want to
do the following steps:
1) In this CL for V8: create a new directory for the clusterfuzz corpus
2) In chromium: use the new corpus directory
3) In v8: clean up the old directory to use it on the trybots.

      [inspector] better stacks for promises · f2bd913c
      kozyatinskiy authored 
      - we should always set creation async stack if it's available regardless existing of current parent async stack,
- we should cleanup parent link iff there is no creation and schedule async stack for parent.

Let's consider example: Promise.resolve().then(x => x).then(x => x), there is three promises which will call following instrumentation:
1) created #1 (Promise.resolve()) - collected stack #1
2) scheduled #1 - collected stack #2
3) created #2 with #1 as parent (first .then) - collected stack #3
4) created #3 with #2 as parent (first .then) - collected stack #4
5) started #2 - use stack #2 as scheduled
6) scheduled #2 - collected stack #6
7) finished #2
8) started #3 - use stack #6 as scheduled
9) scheduled #3 - collected stack #7
10) finished #3

If we collect stacks between step 4 and 5, it's possible to collect scheduled stack #2 but still have creation stack for #2 - stack #3 - so we always need to add creation event if scheduled is collected.

If we collect stacks between created and scheduled we should not remove parent link even if parent was not scheduled yet.
