4f34d353d2 [wasm] Add proposal js-api spec tests to the testrunner
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.

4de8edce07 [mips][wasm] Correct wasm address space limit.
MIPS64 has a user space of 2^40 bytes on most processors, address
space limits needs to be smaller. 256G is ok, but it will cause
many wasm tests get a OOM error.

This patch also skip some tests which need correct IEEE-745 2008
NaN bit patterns on mips.

4df3db7b2e [wasm][ia32] Fix i64tof32 conversion on Windows
On Windows, the FP stack registers are used with less precision.
This causes rounding errors in the uint64 to float32 conversion.

This CL replaces the implementation based on FP stack registers
with an implementation based on bit operations. This implementation
is 2x slower than the original implementation.

An alternative would be to change the precision of the FP stack
registers just for the uint64 to float32 conversion. However, in a
micro-benchmark this is 5-6x slower than the original implementation.
It is also not clear if changing the precision could cause side
effects.

34c8443c88 [wasm][bulk-memory] Check segment bounds lazily
The bulk memory proposal changed behavior of segment initialization
during instantiation. Previously, all segments would be bounds-checked,
after which the segments would be initialized.

The bulk memory proposal removes the up-front check, and always
initializes active segments in order, starting with element segments and
then continuing with data segments. Each active segment is initialized
as-if they were being initialized with the `memory.init` and
`table.init` instructions, so an out-of-bounds initialization may still
modify the memory or table partially.

e3d957e34b [wasm] "fix" critical memory pressure notification
Previously, we sent a critical low memory pressure notification when
attempting to commit WASM code when the code manager was near the
limit for total amount of code allocated.
https://chromium-review.googlesource.com/c/v8/v8/+/1073412 "fixed" that,
but it causes OOMs on Windows.

Since we no longer have the isolate on the code manager, and thus cannot
send this notification on commit, send the notification upon the next
module creation.

This is still not optimal, but should fix OOM issues for lots of
small modules on Windows.

2064c1f920 [wasm][ia32] Add an additional stack check for functions with big frames
This is the ia32 implementation of the CL
https://codereview.chromium.org/2763593002

Original message:

[wasm][arm] Add an additional stack check for functions with big frames.

Stack overflow checks are typically implemented as part of the TurboFan
graph of a function. This means that the stack check code is executed
after frame construction. When a frame is too big, though, there may not
be enough space on the stack anymore to throw the stack overflow
exception after frame construction. With this CL we do an additional
stack check before frame construction for functions with big frames.

As discussed offline with mstarzinger, I do this change currently only
for WebAssembly.

This CL contains only the changes for arm. I will do the other platforms
in separate CLs.

e177068e5c [wasm] Add wasm spec tests to the v8 test runner
The spec tests are stored on a mirror and are downloaded with the DEPS
file. The test files on the mirror are updated with a script which has
to be executed manually.

This CL contains the following changes:

* A script which updates the spec tests and uploads the generated files
  to the mirror.
* Changes to the DEPS file to download the files from the mirror.
* Changes so that tools/run-tests.py can run the spec tests.
