WebAssembly dynamic tiering should be tested with an origin trial. For
the origin trial the feature flag value has to be loaded from blink.
This CL stores the value of the --wasm-dynamic-tiering flag in the
compilation state, from where it gets passed forward to all uses of the
flag. The flag value gets loaded from blink when a new NativeModule is
created.

With dynamic tiering, typically not all functions of a WebAssembly
module get compiled with TurboFan, and therefore the code caching would
never get triggered. With this CL code caching is triggered whenever
{FLAG_wasm_caching_threshold} bytes of TurboFan code are generated.
This new caching event is only triggered when --wasm-dynamic-tiering is

However, when these functions are added to WasmModulBuilder,

Therefore, when ref.func tries to find a function corresponding

Previously we'd treat %_AsyncFunctionReject (and %AsyncFunctionReject)
as side-effect free (in async functions), but that's not correct, since
promise rejections have side-effects (at the very least triggering the
unhandled promise rejection machinery in the browser).
This required a minor refactoring as previously we'd classify functions
as side-effecting or not depending on whether they contain any calls to
side-effecting intrinsics, no matter whether this call is actually
executed or not. That would break REPL mode however if we'd generally
treat all async functions with %_AsyncFunctionReject intrinsic calls as
side-effecting, so instead of performing the intrinsic checks ahead of
time, we now perform the test at execution time.

void. This is confusing; the code is more clear if we require the return
type to be specified.
Aside from src/torque, this change is almost entirely just adding
`: void` until the compiler is happy. However, two intrinsics in
src/builtins/torque-internal.tq have been corrected to declare an
appropriate return type. Those two intrinsics were only used in code
generated within the compiler after the type-checking phase, so we never
noticed that their return types were declared incorrectly.

The V8 Inspector was sending an additional frame as part of async stack
traces for async functions, which pointed to the first executed `await`
in the async function. This is leaking an implementation detail of how
(and more precisely when) the inspector decides to collect this stack
trace. From the users perspective the async part of the stack trace is
supposed to capture what happened _prior to the task_ - meaning in case
of async functions: What lead to the execution of the async function.
This is reflected by the fact that the DevTools front-end (and the V8
Inspector itself) performs post-processing on these async call stacks,
removing the misleading top frame from it. But this post-processing is
not applied consistently to all async stack traces (i.e. the Console
message stack traces don't get this), and potentially also not applied
consistently across consumers of the Chromium debugger backend.
Instead the V8 Inspector now removes the top frame itself and thus
reports `await` consistently with how other async tasks are reported to
debugger front-ends.
Note: This preserves backwards compatibility with old versions of
devtools-frontend, which do post-processing (for the Call Stack) only on
async stack traces marked with "async function", while we now mark these
async stack traces with "await" instead (aligned with what the front-end
is using as user visibile string anyways in the Call Stack section, and
this matching will be updated in a separate follow up CL to look for
"await" instead of "async function").

- Hide the generic DataAt/SetDataAt accessors and replace them by
dedicated accessors. Use the common lower_case naming scheme for
these.
- Shuffle around definitions in js-regexp.h s.t. they are in a
meaningful order.
- Dedupe the source/flags accessors - these fields are stored both
on the instance and on the data array. We keep only accessors for
the instance. Previously, these were disambiguated through naming
oddities (e.g. Pattern() returned data->source).

Original change's description:
> [regexp] Reorganize and deduplicate in the regexp parser
>
> The parser is organized in a somewhat tricky way s.t. it can be
> hard to map the implementation back to the specified grammar.
>
> In particular, the logic for CharacterClassEscape, ClassEscape,
> and CharacterEscape was implemented twice - once inside a character
> class, once outside.
>
> This CL refactors related logic to have only a single implementation.
>
> As a drive-by, fix one related inconsistency related to \k inside
> a character class.
>
> Fixed: v8:10602
