The helper would cause the stack to be unaligned during pushes which caused issues
on Arm64. PushMultipleTimes is only used once by InterpreterEntryTrampoline,
therefore it doesn't make sense to change it's behaviour for --optimize-for-size.

Printing regexp code used to behind the generic --print-code flag, but
there was no way to distinguish between irregexp-generated code; and
printing regexp bytecode was not supported at all (the
--trace-regexp-bytecodes flag *did* exist, but prints the execution
trace at runtime and not the generated bytecode sequence).
This CL adds two new flags:
--print-regexp-code
--print-regexp-bytecode
Regexp code is no longer printed as part of --print-code.
Example output for --print-regexp-bytecode:
generated bytecode for regexp pattern: .(?<!^.)

Currently the backing store and elements kind might not aligned aka
backing store can be dictionary where elements kind is frozen/sealed
element kinds or the other way around. The reason is that
Object.preventExtensions change elements kind to DICTIONARY while
Object.seal/freeze change elements kind to SEALED/FROZEN element kind.
Apply both these operations can lead to that problem as in
chromium:992914
To solve this issue, we avoid Object.preventExtensions to change backing
store to dictionary by introducing new nonextensible elements kind.
These new nonextensible elements kind are handled similar to frozen,
sealed element kinds. This change not only fixes the problem but also
optimize the performance of nonextensible objects.

Reason for the revert is that the breaking at stack overflow does not

We keep the test, slightly modified, and use a better way to

This fixes an invalid assumption when emitting code for matching '^'
(start of line) in multiline regexps and '\b', '\B' in general.
What we used to do: if the current trace's cp_offset (the offset from
the current position) was non-zero, we assumed that we were looking at
subject string index 1 or greater (i.e.: not at the start of the string
or before).
This is no longer valid since cp_offsets can now be negative.
This CL changes the logic to omit start- and bounds-checks only for
strictly positive cp_offsets, where the above assumption still holds.

At the moment we only run the js-api spec tests of the core API on our

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.
