The reference types wasm proposal dropped all subtyping. Subsequently,
the 'anyref' type was renamed to externref.
This changes all references of the *type* anyref to externref.
Additionally, the flag that permits this extension is renamed to
"reftypes" to mirror the proposal name.

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.

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.

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.
