This patch replaces V8's tracing implementation (i.e., the TRACE_EVENT
macros) with the track event base implementation from Perfetto. The
advantages of doing this are:
1) This allows us to remove most tracing-related backend code from V8.
2) V8 can start writing strongly typed trace event arguments, which
are more compact, easier to process and more extensible than legacy
JSON-based trace arguments.
For the time being, we still support the old trace macros when V8 is
embedded into Chrome and other embedders.

At the moment we only run the js-api spec tests of the core API on our
try bots. With the new staging process we want to introduce for
WebAssembly language features, see
https://docs.google.com/document/d/1hB8mpWmzmtaxZ8PuJEkAWLwFqXTjrw7mJ3Ge9W1dB4E,
we also want to run the js-api spec tests of proposals for which we
already staged the implementation. With this CL I do the following
changes:
1) The tools/wasm/update-wasm-spec-tests.sh now copies the js-api spec
tests of the main spec and of the proposals to test/wasm-js/tests,
and then uploads this directory to google cloud storage. The main
spec tests are in test/wasm-js/tests, the proposal tests are in
test/wasm-js/tests/proposals/PROPOSAL_NAME/.
2) Adjust the test-runner in test/wasm-js to run tests in
tests/* instead of data/test/js-api/*. Thereby it also runs the
proposal tests in test/wasm-js/tests/proposals/PROPOSAL_NAME/.
For the proposal tests, the test runner now also adds d8 flags.
3) Remove the dependency to https://github.com/WebAssembly/spec from
DEPS.
4) Cleanup .gitignore and wasm-js.status
5) Disable spec tests we don't pass with the new proposal.

The most important point of IWYU (include-what-you-use) is that each
header includes everything it is using, so that whoever includes that
header does not need to additionally include other things.
This CL adds a script which generates files to automatically check this.
It is automatically invoked during "gclient runhooks" if the
"check_v8_header_includes" variable is set. This script generates a
number of .cc files in the "check-header-includes" directory, together
with a "sources.gni" file which lists all the generated cc files. Each
file includes one header.
If additionally the gn args "v8_check_header_includes" is set, this gni
file is included, and all the generated CC files will be compiled. This
will detect violations of the aforementioned IWYU rule.

This is the V8 equivalent to https://crrev.com/2779193002 and must be landed
before //build/secondary/{gtest,gmock} are removed from Chromium. This started
out as https://crrev.com/2847693002
The changes in tools/ were authored by yangguo@chromium.org and
initially shared in http://crrev.com/2849783003.
GoogleTest (gtest) and GoogleMock (gmock) are now hosted into the same
googletest repository. In order to cope with this, the googletest
repository is now sourced at third_party/googletest.
The file/directory layout of Google Test is not yet considered stable.
To minimize disruption while Google Test stabilizes, Chromium code will
be insulated from third_party/googletest.
* testing/gtest/include/gtest/ and testing/gmock/include/gmock have
been populated with headers that forward into the appropriate
locations of third_party/googletest
* testing/BUILD.gn has been populated with the targets
//testing/gtest(:gtest_main) and //testing/gmock(:gmock_main),
which depend on the appropriate //third_party/googletest targets.
All Chromium code should keep depending on the targets and
headers in testing/{gtest,gmock} for now.

In a recent CL I moved the corpus of the wasm fuzzer and of the
wasm-asmjs fuzzer to a different directory
(wasm_corpus and wasm_asmjs_corpus) so that the corpus is not executed
on the try-bots. With this CL I remove the old corpus from the
.gitignore file.
In addition I removed the hooks for wasm_corpus and
wasm_asmjs_corpus from the V8 DEPS file, because in a V8 checkout
they are not used anyway.
I also added code to the test runner to delete all *.wasm files
from the directories test/fuzzer/wasm and test/fuzzer/wasm_asmjs.
This code should be removed in a week, but it will help my coworkers

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.
