f6ec77c29e [wasm] Update wasm spec tests
This CL also fixes a small bug in the update-wasm-spec-tests.sh script,
as it was not able to handle proposals without additional core spec
tests. It also disables a lot of tests.

3c422d1c5e [snapshot] Clear reconstructable data prior to d8 stress_snapshot run
The serializer currently cannot handle a heap state containing
arbitrary compiled Code objects. As a quick fix for the
--stress-snapshot d8 flag, we clear compiled data from the isolate
prior to the serialize-deserialize-verify pass.

With this change, mjsunit tests pass on x64.

The %SerializeDeserializeNow() runtime function would require more
work, since it is not possible to mutate the heap to this extent while
still preserving a runnable host context and isolate. We will need
another solution there.

Drive-by: Skip the stress_snapshot variant except for the mjsunit
suite.

The multi-value repository was removed from the list of repositories we

multi-value tests which should be removed.

  - Enforce that only declared functions may be returned or used in globals

  - Ensure that table fill does not modify any entries if OOB.

69719dd42b Reland [wasm] Stage wasm-bigint
There was no problem with the original CL. I just had a problem with
my local git branches.

Original message:

The implementation on wasm-bigint has been done, as far as I can tell.
There are no spec tests yet, only an out-dated copy of the original
spec tests which don't pass anymore. Therefore I disabled all the tests
for now and created a tracking bug at https://crbug.com/v8/9673.

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.

99169dbfc3 PPC: [wasm][tests] Add proposal tests to the wasm spec tests
Port cd34523b9b

Original Commit Message:

    With this CL we add proposal tests to the wasm-spec-tests. For this I
    extended the update-wasm-spec-tests.sh script. Additionally to
    generating the spec tests it does the following:

    For each proposal it identifies those tests that are different to the
    spec tests, and then copies those tests also to the wasm-spec-tests
    directory.

    Additionally I adjusted the test runner of the wasm spec test to
    run the proposal tests with the correct flags.

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.
