f2411cf2b9 [nojit] Disable embed tests on noembed builds
These test off-heap builtin call sequences and don't make sense in
noembed builds.

43fff3d7b1 [runtime] Remove %AddNamedProperty and %AddElement
%AddNamedProperty was only used by regression tests, and is easily
replaced by Object.defineProperty (or deleted, in the case of a
cctest that was designed to test it directly).

%AddElement was unused (probably due to the death of array.js).

ccc068d5fd [nojit] Skip the on-heap trampoline for builtin calls
This CL does two things:

1. It introduces Call/JumpCodeObject as the bottleneck for all calls
   to non-heap-constant Code objects; and
2. it dispatches directly to the off-heap entry point for all embedded
   code.

Codegen at runtime remains unchanged to preserve the shorter,
branch-less calling sequence.

Only happened with finalizers to unmodified API wrappers or regular

4bd1215c95 Workaround VS/UCRT fmod bug
Recent versions of the Windows Universal CRT changed the behavior of
fmod for when the first parameter is negative. In particular, a result
of negative zero became positive zero. This is rarely critical but it
causes test failures and may effect some JS test suites or web pages.

The fix is to modify Modulo to check for a result of 0 when the first
parameter is negative and change the result to -0. That fixes four of
the five test failures and the fifth one is fixed by comparing the
results against Modulo instead of std::fmod.

0400fc2049 [heap] Optimize marking of descriptor arrays.
Now a descriptor array tracks the number of descriptors that were
already marked. The marking visitor of a map only marks the subset
of the descriptors that it needs and that are not already marked.

If a descriptor array is shared between M maps and has N descriptos,
then the number of marking operations is reduced from O(M*N) to O(N).

This patch also adds a marking barrier for descriptors.

The marked descriptor counter in a descriptor array is not cleared
after mark-compact GC. Instead, it embeds two bits from the global
mark-compact epoch counter and is considered 0 if the bits do not match
the current value of the global epoch counter.

dde5e3a134 [parser] Detect duplciate lexical declarations in preparser
This changes how rewind upon preparser abort works. It now rewinds to the start
of the parameter scope. In the case of "function X(" it is before the "(". In
the case of arrow functions it's before the start of the arrow function. This
allows us to reparse the arrow function from the start so all parameters are
declared properly.

globals. This includes:

* Properly decode anyref globals.
* Add a FixedArray to WasmInstanceObject to store anyref globals.
* Initialize the FixedArray.
* Generate code for global.get and global set.

This CL does not allow to import globals yet.

11a4da99d2 [Deflake] Fix data-race relating to accessing FLAG_* on worker thread during background compile
The parser object can now be created on a worker thread, therefore we shouldn't access
global FLAGs during the constructor. Instead move them to the ParseInfo constructor
and set the parser fields based on these. Also avoid accessing always_opt flags in
bytecode-flags - instead accessing it in ParseInfo and propagating to the bytecode
generator.

Also gets rid of unused kUntrustedCodeMitigations flag in UnoptimizedCompilationInfo

Parser::MaybeResetCharacterStream calls Scope::ContainsAsmModule which
recursively checks whether a Scope is an asm module or any of its
sub-scopes. This is sub-optimal for deeply nested scopes and many
functions which do not contain any asm modules.

Drive-by-fix:
- rename Scope::asm_module to Scope::is_asm_module

3dbb374938 [test] Fix flaky wasm test and add stable regression test
Remove a DCHECK that got triggered in the rare condition that GC kicks in
during CompilationDependencies::Commit, changing the pretenuring decision,
thus leading to deoptimization. To make sure this rare case is properly
handled, add a new FLAG_pretenure_during_compilation and a cctest that
simulates it predictably.

640d3adf5f [builtins] Remove InternalArray and reduce InternalPackedArray constructors.
InternalPackedArray now only has one constructor variant that expects no
arguments (Chrome's only usage of InternalPackedArray). As such, these TFC
builtins are no longer used and were removed:
- InternalArrayNoArgumentConstructor_Holey
- InternalArraySingleArgumentConstructor_Packed
- InternalArraySingleArgumentConstructor_Holey

On x64.release, this reduces builtins size by ~1.2KB.

Mythri
a36f2593ed Don't use feedback vector to infer IC kind and language mode
Currently, the runtime IC functions deduce the IC kind and the language
mode from the feedback slot kind. To support feedback free execution
(for V8 lite mode and lazy allocation of feedback vectors) we need to
infer the IC kind even when feedback vectors are not present.

To be able to infer the language mode without feedback vectors, this cl
forces context allocation in cases where we raise the language mode in
the middle of a function. The language mode is the stricter of the
language mode on the SFI and the language mode of the current context.

This cl updates the bytecode handlers to check for valid feedback vectors
and to call into runtime if the feedback vector is not allocated. It also
adds new runtime functions to be able to infer the IC kind when there is no
feedback vector. Most of the builtins and handlers remain unchanged because
they are only used when feedback vector is present.

a55803a15d [SFI] Add support for flushing old Bytecode from SharedFunctionInfos.
This change makes the SFI to bytecode link pseudo-weak. The marking visitors
check whether the bytecode is old, and if so, don't mark it and instead
push the SFI onto a bytecode_flushing_candidates worklist. Once marking
is complete, this list is walked, and for any of the candidates who's bytecode
has not been marked (i.e., is only referenced by the shared function info),
the bytecode is flushed and the SFI has the function data replaced with
an UncompiledData (which overwrites the flushed bytecode array).

Since we don't track JSFunctions, these can still think the underlying
function is compiled, and so calling them will invoke
InterpreterEntryTrampoline. As such, logic is added to
InterpreterEntryTrampoline to detect flushed functions, and enter
CompileLazy instead.

f68ee6e7e4 [typedarrays] Use Detach instead of Neuter
This is purely a renaming change. The ES spec uses the term 'detach'
for the process of removing the backing store of a typed array, while
V8 uses the historical term 'neuter'. Update our internal implementation,
including method names and flag names, to match the spec.

Note that some error messages still use the term 'neuter' since error
messages are asserted by some embedder tests, like layout tests.

e42b547b96 [wasm] Serialize without accessing any Isolate
We need to be able to serialize a NativeModule, which is not bound to
any Isolate. Hence we should not want to pass any Isolate to the
serializer. This CL removes the dependence by not using the
ExternalReferenceTable from the Isolate, but instead using its own
ExternalReferenceList for serialization and deserialization. This
ExternalReferenceList only contains isolate-independent external
references.

b89d4249c0 [nojit] Migrate JSEntry variants to builtins
This migrates the JSEntryStub to three dedicated builtins:

JSEntry
JSConstructEntry
JSRunMicrotasksEntry

Drive-by: Tweaks to make the code isolate-independent (e.g. using the
correct macro assembler method to load and store external references
through the kRootRegister).
Drive-by: The context slot on x64/ia32 must be set up after
kRootRegister is initialized, so we first reserve the slot and later
load its value.
Drive-by: Update all remaining comments referencing JSEntryStub.

a0858cf0ca [regexp] Add use counters for IsRegExp
A spec change to simplify IsRegExp has been proposed:

https://github.com/tc39/ecma262/pull/1318

This CL adds use counters for cases in which the spec change would
alter behavior:

1. o[@@match] is trueish but o is not a JSRegExp
2. o[@@match] is falseish (but not undefined) and o is a JSRegExp

This is the V8 side of required changes.
The Chromium-side CL: https://crrev.com/c/1360730

Drive-by: TNodeify IsRegExp.

16afa0a226 [api][wasm] Rename WasmCompiledModule to WasmModuleObject
A WasmModuleObject represents an instance of WebAssembly.Module. It is
called WasmModuleObject internally, so also use that name externally.

We still have a typedef for WasmCompiledModule which will be deprecated
once chromium has been updated to use WasmModuleObject.

2f852e5e54 [factory] Make sure large code objects actually go to large code space
If the size of a large code object is larger than
kMaxRegularHeapObjectSize, then it should be allocated in the large code
space. Currently if the size is > kMaxRegularHeapObjectSize but <
512000, then it can still be allocated in the normal code space.
