2021d4ef2c [DevTools] Switch inspector-test.cc to use the CBOR encoded inspector state.
The main change here is that in isolate-data.h, I'm switching from stateJSON to state.
This routine returns a CBOR encoded state cookie, which is also what we already
use in Chromium (blink).

In inspector-test.cc, I then put this byte vector into a V8 String,
and to make this roundtrip, change the extraction routine to get the
bytes. It's a little weird to store arbitrary bytes inside a v8 string,
but it appears to work fine because these bytes end up in the 8 bit portion,
much like isolatin characters would.

baf84940f4 [wasm] Display wasm globals in the inspector
They are added under the global scope object, as follows:

  {
    "memory": ...,
    "globals": {
      "global#0": ...,
      "global#1": ...,
      "global#2": ...,
    }
  }

We currently don't have any way to name globals in the wasm binary
format, but it is possible to extend the name section with these names
in the future.

b901591015 inspector: added Debugger.setInstrumentationBreakpoint method
There are two possible type:
- scriptParsed - breakpoint for any script,
- scriptWithSourceMapParsed - breakpoint for script with
  sourceMappingURL.

When one of the breakpoints is set then for each matched script
we add breakpoint on call to top level function of that script.

4b0f9c856e [cleanup] Use Vector::begin instead of Vector::start
Our {Vector} template provides both {start} and {begin} methods. They
return exactly the same value. Since the {begin} method is needed for
iteration, and is also what standard containers provide, this CL
switches all uses of the {start} method to use {begin} instead.

Patchset 1 was auto-generated by using this clang AST matcher:
    callExpr(
        callee(
          cxxMethodDecl(
            hasName("start"),
            ofClass(hasName("v8::internal::Vector")))
        ),
        argumentCountIs(0))

Patchset 2 was created by running clang-format. Patchset 3 then
removes the now unused {Vector::start} method.

ba081a32d2 [inspector] Add test for getPossibleBreakpoints on embedded code
This tests calling Debugger.getPossibleBreakpoints on a user function
embedded into the startup snapshot.

Currently, this fails because inspector does not know how to handle
scripts without an associated context. The test should be updated
once we have a fix.

9550604183 [class] Expose private fields through GetPrivateFields
This will allow the devtools UI to display private fields on the scope
panel.

Instead of extending GetInternalProperties, we expose a separate
GetPrivateFields method on the debug interface. This allows us to do
better type checking, for example, we can directly cast to a
v8::Private as this can only contain private fields.

This also allows us to have better constraints on the input type --
v8::Object, as opposed to a v8::Value.

The KeyAccumulator is extended to collect private names for the
PRIVATE_NAMES_ONLY PropertyFilter.

bab6615155 [inspector] Add tests for Debugger domain
New tests added for these calls:

* evaluateOnCallFrame
* setAsyncCallStackDepth
* setBreakpoint
* setVariableValue

For setAsyncCallStackDepth, this change updates the test to manufacture async callstacks in a different way so that there is more than one. The previous promise chain method was broken by f61facf.

74571c80a9 Fix preview of set entries
Set entries return an array with the value as first and second entry.
As such these are considered key value pairs to align with maps
entries iterator.
So far the return value was identical to the values iterator and that
is misleading.

This also adds tests to verify the results and improves the coverage
a tiny bit by testing different iterators.

08f68102f8 [parser] Allow declaring variables without a proxy
Declare Variables with a name and position, rather than by passing
through a VariableProxy. This allows us to not create dummy proxies
for things like function declarations, and allows us to consider those
declarations unused.

As a side-effect, we also have to check if a variable is unused in the
bytecode generator (as it will no longer be allocated), and we end up
skip generating code/SFIs for dead variables/functions.

This removes the iteration protocol from the parser entirely, and opens
up future possibilities for more bytecodes implementing the various

1740bc7bf6 [wasm] Fix maximum value length in scope info
i64 values can be up to 20 characters long (19 + sign), plus we need
one character for the terminating null character. Thus the previous 18
needs to be increased to 21.
Also extend the test to check the longest possible i64 values.

5e725a2b43 [parser] Don't desugar destructuring declarations.
Emit a single destructuring assignment for destructuring declarations,
which can be desugared by the bytecode generator. This allows us to
remove destructuring desugaring from the parser (specifically, the
pattern rewriter) entirely.

The pattern "rewriter" is now only responsible for walking the
destructuring pattern to declare variables, mark them assigned, and
potentially rewrite scopes for the edge case of parameters with a sloppy
eval.

Note that since the rewriter is no longer rewriting, we have to flip the
VariableProxy copying logic for var re-lookup, so that we now pass the
new VariableProxy to the variable declaration and leave the original
unresolved (rather than passing the original through and rewriting to a
new unresolved VariableProxy).

This change does have some effect on breakpoint locations, due to some
of the available information changing between the parser and bytecode
generator, however the new locations appear to be more consistent
between assignments and declarations.

09674b9283 WIP: [parser] Fix arrow function name inferring
This is a reland of part of
https://chromium-review.googlesource.com/c/v8/v8/+/1397664.

It drops the explicit fni_.Infer() call after parsing arrow functions. We'll
want to avoid inferring if the arrow function is an argument to a function
call.

It also avoids adding the single argument of "name => " to the inferred name.

9365d0904e [coverage] Rework continuation counter handling
This changes a few bits about how continuation counters are handled.

It introduces a new mechanism that allows removal of a continuation
range after it has been created. If coverage is enabled, we run a first
post-processing pass on the AST immediately after parsing, which
removes problematic continuation ranges in two situations:

1. nested continuation counters - only the outermost stays alive.
2. trailing continuation counters within a block-like structure are
   removed if the containing structure itself has a continuation.

7e5cac2cf3 Make termination exception more consistent.
Termination exceptions tear down V8 to the bottom-most V8 call. If there is a
v8::TryCatch scope around that call, it returns true for HasTerminated() and
HasCaught(). However, Isolate::IsExecutionTerminating() returns false and we
can call into V8 from still inside the v8::TryCatch scope.

Changes that this patch introduces:
 - You need to leave the v8::TryCatch scope around the bottom-most call to
   reset the termination state, in order to resume.
 - Explicitly check for termination exception and reporting it through the
   DevTools protocol after Runtime.evaluate and Debugger.evaluateOnCallFrame.

bf2f0a0227 [builtins] Support embedded builtins in nosnapshot builds
This CL adds support for embedded builtins in nosnap builds by creating
and setting an 'embedded blob' after builtin generation. Unlike
snapshot builds, the blob is not embedded into the .text section but
located on the C++ heap.

This makes nosnap builds more consistent with mksnapshot, and allows us
to simplify there and in serializer cctests.

Complications arise from the different workflows we need to support:

1. the standard mksnapshot build process,
2. nosnap builds (which reuse the blob created by the first Isolate),
2. and tests with various complicated serialization workflows.

To cover all of these cases, this CL introduces two knobs to twiddle:

1. A 'sticky' embedded blob which overrides compiled-in default
   embedded blobs at Isolate setup.
2. The blob lifecycle can be managed manually or through refcounting.

These are described in more detail in isolate.cc.

b11cedb472 [inspector] restore console.table limits
`console.table` used to have a 1k limit on preview properties, which
regressed to 100 during refactoring.

This CL restores the 1k limit, and ensures that `buildEntryPreview`
does not use the 1k limit.

6c3d784c16 Rename fields to names or members
Rename variables and flag names so that the classes can be reused
by private methods implementation.

In particular:

Rename "fields" to "members" in the initializer so that we can
initialize both fields and private methods/accessors there,
for example:

instance_fields_initializer -> instance_members_initializer
InitializeClassFieldsStatement -> InitializeClassMembersStatement

Rename "private field" to "private name" for the private symbols
used to implement private fields so that we can use them to
store private methods/accessors later as well, for example:

private_field_name_var -> private_name_var
NewPrivateFieldSymbol -> NewPrivateNameSymbol

The follow-on is in
https://chromium-review.googlesource.com/c/v8/v8/+/1301018

The design doc is in
https://docs.google.com/document/d/1T-Ql6HOIH2U_8YjWkwK2rTfywwb7b3Qe8d3jkz72KwA/edit?usp=sharing

986aa36b1f [builtins] Add Array.p.join fastpath for single element array.
This is resurrecting an optimization from the pre-torque version.
Avoid allocating another sequential string for the result when there's only one
element, just return the ToString-ed element.  This not only saves time writing
to this destination string, but also reduce GC pressure.

The System Health Memory Benchmark (load:media:google_images) exposed this missing
optimization with a 15% regression in memory usage.  Very large external strings
were being copied into V8's heap as sequential string.

Instead of getting the bytecode array from the SFI, get it from the frame instead

fact that the bytecode array was on the frame will retain it strongly, however it

66daabcca9 inspector: generate custom preview using native code
Full custom preview generation is moved to custom-preview file
including frontend part. New custom preview implementation returns
body getter function instead of bind function, formatter and config
objects. Body getter function calls formatter.body(object, config)
and returns json ML.

230dd86ce6 [Class] Fix debug scope iteration for class fields
When trying to print the scope information for the class fields
initializer function, the debugger asks the parser to parse the class
literal as a function literal (to get the scope info) ... which
doesn't quite work.

Instead of adding support for parsing the class literal, we just short
cicruit this parsing step by just returning an empty context.

This works fine because initializer function doesn't have any
variables in it's local scope.

The one caveat is that the objects in the scope above this function
(like the global) are now missing. This trade off is possibly fine
for now, as adding parsing support for class literal to only produce
would be a lot of code for not enough use.

As a follow up to this change, the devtools UI needs to be updated to
handle this empty context cleanly. Currently, it doesn't show the
`this` object if no context exists even if the `this` object is
correctly passed to the UI from the backend.

0038e5f05f [async] Improve async function handling.
This change introduces new intrinsics used to desugar async functions
in the Parser and the BytecodeGenerator, namely we introduce a new
%_AsyncFunctionEnter intrinsic that constructs the generator object
for the async function (and in the future will also create the outer
promise for the async function). This generator object is internal
and never escapes to user code, plus since async functions don't have
a "prototype" property, we can just a single map here instead of tracking
the prototype/initial_map on every async function. This saves one word
per async function plus one initial_map per async function that was
invoked at least once.

We also introduce two new intrinsics %_AsyncFunctionReject, which
rejects the outer promise with the caught exception, and another
%_AsyncFunctionResolve, which resolves the outer promise with the
right hand side of the `return` statement. These functions also perform
the DevTools part of the job (aka popping from the promise stack and
sending the debug event). This allows us to get rid of the implicit
try-finally from async functions completely; because the finally
block only called to the %AsyncFunctionPromiseRelease builtin, which
was used to inform DevTools.

In essence we now turn an async function like

```js
async function f(x) { return await bar(x); }
```

into something like this (in Parser and BytecodeGenerator respectively):

```
function f(x) {
  .generator_object = %_AsyncFunctionEnter(.closure, this);
  .promise = %AsyncFunctionCreatePromise();
  try {
    .tmp = await bar(x);
    return %_AsyncFunctionResolve(.promise, .tmp);
  } catch (e) {
    return %_AsyncFunctionReject(.promise, e);
  }
}
```

Overall the bytecode for async functions gets significantly shorter
already (and will get even shorter once we put the outer promise into
the async function generator object). For example the bytecode for a
simple async function

```js
async function f(x) { return await x; }
```

goes from 175 bytes to 110 bytes (a ~38% reduction in size), which
is in particular due to the simplification around the try-finally
removal.

Overall this seems to improve the doxbee-async-es2017-native test by
around 2-3%. On the test case mentioned in v8:8276 we go from
1124ms to 441ms, which corresponds to a 60% reduction in total
execution time!
