ed9b2072a6 [inspector] reworked async instrumentation for promises
Old instrumentation was designed to collect promise creation stack and
promise scheduled stack together. In DevTools for last 6 months we
show only creation stack for promises. We got strong support from users
for new model. Now we can drop support for scheduled stacks and
simplify implementation.

New promise instrumentation is straightforward:
- we send kDebugPromiseThen when promise is created by .then call,
- we send kDebugPromiseCatch when promise is created by .catch call,
- we send kDebugWillHandle before chained callback and kDebugDidHandle
  after chained callback,
- and we send separate kDebugAsyncFunctionPromiseCreated for internal
  promise inside async await function.

Advantages:
- we reduce amount of captured stacks (we do not capture stack for
  promise that constructed not by .then or .catch),
- we can consider async task related to .then and .catch as one shot
  since chained callback is executed once,
- on V8 side we can implement required instrumentation using only
  promise hooks,

Disadvantage:
- see await-promise test, sometimes scheduled stack was useful since we
  add catch handler in native code,

Implementation details:
- on kInit promise hook we need to figure out why promise was created.
  We analyze builtin functions until first user defined function on
  current stack. If there is kAsyncFunctionPromiseCreate function then
  we send kDebugAsyncFunctionPromiseCreated event. If there is
  kPromiseThen or kPromiseCatch then only if this function is bottom
  builtin function we send corresponded event to inspector. We need it
  because Promise.all internally calls .then and in this case we have
  Promise.all and Promise.then on stack at the same time and we do not
  need to report this internally created promise to inspector.

0f2223c894 [test] Refactor getting test outcomes from statusfile.
Filtering by status file split to four parts:
1. Getting outcomes - reads both variant dependent and
independent outcomes, no more need to do it twice.
2. Checking unused rules - has a switch to check only variant
dependent/independent rules.
3. Reading flags - if outcome starts with '--' it is treated as a flag.
4. Actual filtering.

Outcomes removed from the testcase object, can be accessed
by call to its testsuite.

09323a6a17 [wasm] Use activations of the interpreter in the fuzzers
Typically the interpreter returns 0xdeadbeef to indicate an exception.
However, for stack overflows a normal exception is used. The interpreter
requires an activation, however, to deal with normal exceptions. With
this CL we start an activation before we execute the fuzzer input in the
interpreter.

d43c6e59fc Decouple SourcePositionTableBuilder from Zone
Currently the SourcePositionTableBuilder requires a Zone because it
holds a ZoneVector<byte> of the encoded entries. Since ZoneVector is a
suboptimal data structure anyway, and for Liftoff we don't even have a
Zone allocated currently, this CL replaces the ZoneVector by
std::vector.

6607bac5f4 [wasm-streaming] Fix function index calculation
The index of a function in the WasmModule data structure is offset by
the number of imported functions in the module. The {DecodeFunctionBody}
function of the module decoder, however, requires the function index
without this offset. The streaming processor mixed up these two ranges
of function indices. This is fixed in this CL.

c71fd20cf9 [wasm] Data structures for JIT-ing wasm to native memory.
This CL introduces the structures for JIT-ing wasm on the native heap.
They are described in detail at go/wasm-on-native-heap-stage-1

Briefly:
- WasmCodeManager manages memory for modules and offers an interior
pointer lookup (i.e. PC -> WasmCode)
- WasmCode represents code, including reloc info. It holds wasm
specific data, like function index, and runtime information, like trap
handler info.
- NativeModule manages memory for one module.

Tests cover the allocation and lookup aspects, following that current
regression tests cover the JITed code. A separate CL will enable JITing
using the new data structures.

d9b42b7b34 [wasm] Handle modules without code in streaming compilation
Streaming compilation started the compilation of a module at the
beginning of the code section. However, there exist valid modules which
do not contain a code section. In this CL we check for the existence of
a code section when we finish the stream. We do this by checking if the
module compiler in the AsyncCompileJob exists, because the module
compiler gets initialized at the beginning of the code section.

If we detect that compilation has not been started because there was no
code section, then we start compilation when the stream finishes.

365bb5bb4a [regexp] Add a CSA fast path for replace with global regexp.
For simple replacement strings without $ characters, we can do the
replacement in CSA for a global regexp. This is a common case because
this is currently the most widely used way to 'replaceAll' in a string.

This CL speeds up the test case in the linked bug by 13%.

a9a1671345 [cleanup] Rename "array protector" to "no elements protector".
The "array protector" now guards the Object.prototype, the
Array.prototype and the String.prototype, so the name was a
bit misleading nowadays. So the new name "no elements protector"
was chosen.

09b53eef4c [api] Make running scripts in AddMessageListener callback work in debug mode
The existance of an `AllowJavascriptExecutionDebugOnly` scope in
`Isolate::ReportPendingMessages()` indicates that the API supports
running arbitrary JS code in a `AddMessageListener` callback.

Currently, this can fail in debug mode: The
`!isolate->external_caught_exception()` condition is checked when
entering API methods inside such a handler. However, if there is
a verbose `TryCatch` active when the exception occurs, this
check fails, and when calling `ToString()` on the exception object
leaves a pending exception itself, the flag is re-set to `true`.

Fix this problem by clearing the flag and the pending exception if
there was one during `ToString()`. This matches the code a few lines
up in `messages.cc`, so the exception state is now consistent
during the callback.

This currently makes a Node.js test fail in debug mode
(`parallel/test-error-reporting`).

977da55033 [bigint] Encapsulate internals in MutableBigInt
This CL creates the invariant that the BigInt class treats
BigInt objects as immutable. Writing to new BigInt objects
as part of their construction is done by the MutableBigInt
helper class, which in turn is hidden as an implementation
detail in bigint.cc.
As a side effect, this refactoring enforces right-trimming
checks for all newly created BigInts, and ensures that all
BigInt allocations possibly exceeding kMaxLength check for
this case and throw a RangeError instead of crashing.
