28a9dc2b81 Remove JS natives support, step 1
The natives blob is deprecated and will be removed in the next
release.

This commit does two things, 1. it disables the v8_extra_library_files
gn argument which will make building natives_blob.bin through gn
impossible; 2. it marks API functions associated with the natives blob
as V8_DEPRECATE_SOON.

Embedders should remove any uses of SetNativesDataBlob and replace all
calls to

 InitializeExternalStartupData(const char*, const char*)

with the new function

 InitializeExternalStartupDataFromFile(const char*)

Step 2 is to mark API functions as V8_DEPRECATED.
Step 3, in the next V8 release, is to remove these functions and all
other natives support in V8.

36ab7afb9e Improve JavaScript debugging in d8
Adds ability to pause JavaScript debugger from d8 by defining a global function
`handleInspectorMessage` which should block waiting for a new inspector message,
and `send` it afterwards.

Additionally, adds a simple helper script that, when invoked via `websocketd`
as per instructions, can be used for debugging `d8` using Chrome DevTools
(inspecting script sources, pausing, stepping over, etc.).

6612943010 [regexp] Bytecode peephole optimization
Bytecodes used by the regular expression interpreter often occur in
specific sequences. The number of dispatches in the interpreter can be
reduced if those sequences are combined into a single bytecode.

This CL adds a peephole optimization pass for regexp bytecodes.
This pass checks the generated bytecode for pre-defined sequences that
can be merged into a single bytecode.

With the currently implemented bytecode sequences a speedup of 1.12x on
regex-dna and octane-regexp is achieved.

39cc400dea [top-level-await] Add support for top level await to d8
This cl adds support for top level await to d8, but still
does not allow top level await through parsing.
Unfortunately, due to that restriction this cl has no automated
tests, but I added a 'top-level-await' variant and manually
confirmed it passes locally.

1d3c4975be [tools] Use instance types of known Maps in v8_debug_helper
If we can read an object's Map pointer but not any data from the Map
itself, we may still be able to accurately describe the object's type if
the Map pointer matches one of the known Maps from the snapshot.
GetObjectProperties uses that data in one of two ways:
- If it is sure that the Map pointer matches a known Map, then it uses
  the type from that Map and continues as if it read the type normally.
- If the Map pointer is at the right offset within a heap page to match
  a known Map, but the caller didn't provide the addresses of the first
  pages in Map space or read-only space, then the type of that Map is
  just a guess and gets returned in a separate array. This gives the
  caller the opportunity to present guessed types to the user, and
  perhaps call again using the guessed type as the type hint.

0721118d70 [snapshot] Allow an empty v8_extra_library_files
... and do not artificially add at least one dummy.js file.

Until this CL we used to ensure the existence of at least one 'extra
native' by appending a short dummy.js file if v8_extra_library_files
was empty. This file is uselessly compiled and run at startup.

This CL removes that mechanism along with a minor tweak to handle an
empty natives blob.

167a89469d [heap] Split old-to-new remembered set
Split OLD_TO_NEW remembered set and add OLD_TO_NEW_SWEEPING. The
OLD_TO_NEW remembered set is moved to OLD_TO_NEW_SWEEPING during
mark-compact. OLD_TO_NEW_SWEEPING is then modified by the sweeper.
Before using the page again, OLD_TO_NEW and OLD_TO_NEW_SWEEPING are
merged again.

This means only the main thread modifies OLD_TO_NEW, the sweeper only
removes entries from OLD_TO_NEW_SWEEPING. We can use this property
to make accesses non-atomic in a subsequent CL.

0a31d508f1 [tools] Teach v8_debug_helper where heap spaces start in ptr-compr mode
v8_debug_helper attempts to flag known object pointers when it can
recognize them, even if the memory pointed to is not available in the
crash dump. In ptr-compr builds, the first pages of the map space,
read-only space, and old space are always at the same offsets within the
heap reservation region, so we can more easily detect known objects.

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.

2ccca6c5ac [tools][torque] Include string values in GetObjectProperties responses
This change provides a quick way to see string contents in postmortem
debugging sessions, without digging through a (possibly very large, in
the case of ConsString) tree of properties. As well as being convenient
for inspecting String objects, this functionality will also be necessary
for displaying property names on JSReceiver objects. In order to support
custom behaviors for specific classes, this change extends the existing
generated debug reader classes with a visitor pattern.

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.
