ce409375b3 [sfi] Reduce FunctionTokenPosition and ExpectedNofProperties to 16 bits.
Changes SharedFunctionInfo to store a function_token_offset, relative
to the start_position, instead of the full function_token_position.
This enables us to reduce both FunctionTokenPosition and
ExpectedNofProperties to 16 bits each, saving 32 bits per SFI.

93f59deef8 [array] Throw TypeError for read-only properties on fast-path
This CL changes the NumberDictionary fast-path for Array.p.sort to
throw a TypeError when trying to write to a read-only property.

Previously, the fast-path simply bailed to the slow-path which could
swallow the TypeError by accident. I.e. because the fast-path could
leave the array in an inconsistent state that is already sorted.

Example:

let arr = new Array(10);
Object.defineProperty(arr, 0, {value: 2, writable: false});
Object.defineProperty(arr, 2, {value: 1, writable: false});
arr.sort();

The pre-processing step will move the value 1 to index 1: {0: 2, 1: 1}
When trying to swap those 2 values, the fast-path will write the 2 at
index 1, then try to write the 1 at index 0 and fail, bailing to the
slow-path. As the array looks like {0: 2, 1: 2} its already sorted
and the TypeError will not be thrown.

34225a6afb Fix overzealous assert in CallOrConstructVarArgs
For spread calls with arrays with double elements but zero length,
we skip the box-as-heapnumber step; so in this corner case the
Call builtin sees a FixedDoubleArray, which is fine because it
doesn't read any of the raw double values from it.
This patch doesn't change the implementation, it only updates the
assert to match reality.

currently the scanner consumes the "e+" part (as it thinks

6c585ef0e8 [runtime] perform type conversion earlier in IntegerIndexedElementSet
When storing an indexed property in a typed array, it's necessary to
convert the value to a Number (or to a Bigint) before performing the
bounds check, per
https://tc39.github.io/ecma262/#sec-integerindexedelementset.

This CL adds appropriate type conversions in
Object::SetPropertyInternal (which technically is reached after the
bounds check has already occurred, but this isn't observable yet ---
In the future, once OOB accesses on TypedArrays actually throw, this
will need to be refactored again), and in StoreFastElementStub, and
ElementsTransitionAndStoreStub (via CSA::EmitElementStore).

The change was not necessary in TurboFan, as
JSNativeContextSpecialization already performs the value conversion
before the boundscheck.

The result is some fixed test262 tests, and some new test coverage
for this behaviour in mjsunit.

75f14dbffc [regexp] Remove exhaustive Script_Extensions tests
The upstream test suite for Unicode property escapes [1] is exhaustive
and is updated soon after every new release of the Unicode Standard.
It is then upstreamed into Test262.

This patch simplifies our own Script_Extensions tests and the script
used to generate them. Now, only a few code points are tested for each
Script_Extension. This avoids unnecessary friction every time ICU
is updated based on a new Unicode version.

ada648006b [Liftoff] Fix register use count
In {SetLocalFromStackSlot}, we decrement the use count of the register
in the target slot without updating this slot, and then call
{GetUnusedRegister}. At that point, the register use counts do not
match the cache state, which leads to errors later on.
This CL fixes this by marking the target slot as a stack slot after
reducing the register use count.

It also adds a Validation which helped to find that error and will
catch similar errors earlier.

3bcf2b83eb [array] Change Array.p.sort bailout behavior from fast- to slow-path
This CL fixes a bug where execution would continue on a fast-path
even though a previous recursion step bailed to the slow path. This
would allow possibly illegal loads that could leak to JS.

Drive-by change: Instead of bailing to the slow-path on each recursion
step, we now bail completely and start the slow-path afterwards.

da03262e4c [wasm] Fix for exporting imported mutable globals
Mutable globals are stored in the instance differently, so they must be
exported differently as well.

Also fix a counting bug that occurred when a module contained a global
and an imported mutable global (CalculateGlobalOffsets is called
twice).

3896cdc25c Reland "[array] Use random middle element to determine pivot during sorting"
This is a reland of 91bab5588c

This CL contains two major changes w.r.t to the original CL:

The random state is removed from the Smi root list and we pre-seed the RNG
on each sort with the length of the array.

To cut down on the length of the arguments list and to keep track of the
random state across recursive calls, we move most of the sort arguments into
a FixedArray and reload from the array for each recursion.

Original change's description:
> [array] Use random middle element to determine pivot during sorting
>
> This CL adds a "random state" to the Smi Root list and implements a
> basic Linear congruential pseudo random number generator in Torque.
>
> The RNG is used to determine the pivot element for sorting. This will

>
> Drive-by-fix: Make sorting of ranges and execution pauses for profviz
> deterministic by adding a secondary sorting criteria.

b984b70c3a [wasm] Fall back on bounds checks when guarded memory unavailable
This CL adds the simplest version of a trap handler fallback. At
instantiation time, we check whether the module was compiled to use
trap handlers and the memory is guarded. If the memory is not guarded
but the module is supposed to use trap handlers, we recompile the
module with bounds checks so that we can use an unguarded memory.

The compiled module is replaced with a bounds checking version, meaning
future instances from this module will also use bounds checks.

Some likely desirable features that are current missing but can be
added future CLs include:
* Disabling trap handler mode entirely.
* Recompiling all old instances so that trap handler and bounds checked
  code does not coexist in the same process.

86a2720763 [test] Make assertThrowsEquals use assertSame
The typical use of assertThrowsEquals is to check that a specific
object is thrown. However, assertEquals only does a proper equality
check for primitive types, not for complex types. Using assertSame
does a reference equality check on objects, which is more what you
would expect from assertThrowsEquals. For exception kind testing,
assertThrowsEquals actually did not work correctly, assertThrows is
better for that case.

c96ac82c50 [wasm] Make stack check independent of the Isolate.
This makes stack checks in WasmCode independent of the underlying
Isolate by loading the limit address from the WasmInstanceObject instead
of embedding it into the instruction stream. It hence removes the last
use of the Isolate field from WasmGraphBuilder.

Additionally this introduces the notion of a "runtime stub" which
represents stub code global to the NativeModule that can be directly
called from each WasmCode in the same module. These stubs can act as
trampolines via which Isolate-independent WasmCode can enter other V8
builtins or runtime functions that remain Isolate-dependent. They will
eventually replace the current "trampoline" in a NativeModule.

53d4dfc377 [sfi] Compress function arg counts to 16 bit
Compress the parameter count (and function length) stored in
SharedFunctionInfo to a uint16_t. This limits us to 2^16 - 1 parameters
per function, minus one for the "don't adapt arguments" sentinel value,
which is one fewer than Code::kMaxArguments was already. Anyway, 65534
arguments should be enough for anyone!

This drops SFI size by 4 bytes.

fabb514087 [wasm] Avoid embedding {null} values in WasmCode.
This loads references to {null} values from the instance object instead
of embedding them into the generated code. It is one step towards making
the {WasmCode} objects independent of the Isolate.

Note that this also fixes an issue with the serializer/deserializer that
failed to properly serialize {null} values and accidentally collapsed
them to {undefined} values instead.

8a95da2415 [wasm] Reimplement WebAssembly.instantiate without desugaring
At the moment, WebAssembly.instantiate(bytes) is implemented by
desugaring it to WebAssembly.compile(bytes).then(WebAssembly.instantiate).
The problem is that the {then} in this snippet is observable. With this
CL I introduce a CompilationResultResolver which allows to do the
desugaring internally and thereby make the {then} unobservable.
Unfortunately the result of WebAssembly.instantiate(bytes) is different
than the result of WebAssembly.instantiate(module). Therefore I also
introduced an InstantiationResultResolver for symmetry with
WebAssembly.compile.

a6c71508c5 [typedarray] Change TypedArray.p.sort implementation.
This CL uses the new function pointers and generic features of Torque
to improve the performance of TypedArray.p.sort.

Instead of one Load/Store builtin that dispatches at runtime based on
the element kind, there are now many small builtins (one for each
element kind). The sorting algorithm then uses function pointers to
those small builtins, which get set once.

Changes in the relevant benchmarks:
