996cf21954 [tools] Generate additional variant for FAIL_PHASE_ONLY tests
The additional variant does not use wrapper disabling phase tests and negated
outcome processor. This allows to ensure that tests marked FAIL_PHASE_ONLY, do
actually fail without it.

4084185b3c [wasm] Implement memory.init and memory.drop
`memory.init` copies bytes from a passive data segment to linear memory.

`memory.drop` is an instruction that informs the wasm VM that the instance no
longer needs access to the passive data segment.

Information about the passive data segments, including their contents, length,
and whether they are dropped, is stored in the `WasmInstanceObject` as primitive
arrays.

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.

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.

9f3c996d34 [wasm] Group anyref parameter
To allow any-ref parameters, we have to make sure that any-ref stack
parameters get seen by the GC. This CL is a first step into that
direction. The goal of this CL is to group any-ref parameters at the
stack side of the parameters. This means that in the stack frame
iterator we do not need information about where anyref parameters are
in the stack frame. We only need information about how many anyref
parameters there are at the bottom of the stack frame.

dc6eed6a4e [compiler] Relax too strict debug assert.
We assert that loops always have effect phis because there must be
a stack check in every loop. However, with generators, the stack check
may end up outside of loop because the dispatch switch is built first
(while the dispatch switch will also keep the loop backedge alive).

The logic for creating effect phis is already in the code, so
removing the dcheck should be fine.

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.

Fix and re-enable tests for WebAssembly's memory/constructor and

to validate initial and maximum properties.

The initial property is now required, by the switch to the Web IDL
specification. Most of the input validations errors are now considered
TypeError instead of RangeError.

The WasmTableObject and WasmMemoryObject APIs use more consistently uint32_t
to ensure integer range and remove the need for bounds checks.

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.

07011cc4f0 Replace %RunMicrotasks with %PerformMicrotaskCheckpoint
This replaces Runtime_RunMicrotasks with Runtime_PerformMicrotaskCheckpoint.

RunMicrotasks forcibly runs Microtasks even when the microtasks are suppressed,
and may causes nested Microtasks in a problematic way. E.g. that confuses
v8::MicrotasksScope::IsRunningMicrotasks() and GetEnteredOrMicrotaskContext().

OTOH, PerformMicrotaskCheckpoint() doesn't run cause the failure as it
respects the microtask suppressions.

As all existing tests don't call RunMicrotasks() in the suppressed situation
(like Promise.resolve().then(()=>{%RunMicrotasks();})), this change should
not affect to these tests.

f27ac2806c [turbofan] Pin pure unreachable values to effect chain (in rep selection)
Currently, if we lower to a pure computation that is unreachable because
of some runtime check, we just rename it with DeadValue. This is
problematic if the pure computation gets later eliminated - that allows
the DeadValue node float above the check that makes it dead. As we
conservatively lower DeadValues to debug-break (i.e., crash), we
might induce crash where we should not.

With this CL, whenever we lower an impossible effectful node (i.e., with
Type::None) to a pure node in simplified lowering, we insert an
Unreachable node there (pinned to the effect chain) and mark the
impossible node dead (and make it depend on the Unreachable node).

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.

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.

148ef606a7 [wasm] Load thread-in-wasm flag from the isolate
The existing implementation embedded an isolate-specific pointer to the
thread-in-wasm flag in the wrapper code. However, when the module code
is shared among multiple workers, this can mean that the workers
share the same thread-in-wasm flag.

With this change we load the pointer to the flag at runtime from the
current isolate. Thereby the correct flag is used even when the same
code is executed on different workers.

Note that we could access the right flag address by going through the
root register. However, changing the code generation to use the root
register requires some inconvenient steps:
* Pass the isolate to the pipeline again, which we don't want.
* Change the WasmCallDescriptor to allow the use of the root register
  for wrappers but not for other code.
To avoid these issues, and allow the CL to be easy to merge back, we
got for the changes proposed here.

that don't make sense, we should bail out of unwinding and return false.

Page::kPageSize is 524288
MemoryAllocator::GetCommitPageSize() returns 65536 on ppc

ObjectEndOffsetInCodePage() returns 458752
ObjectStartOffsetInCodePage() returns (65536 + 65536) => 131072

Therefore, memory = 327680, which is less than
kMaxRegularHeapObjectSize(507136), which causes the DCHECK to fail.

e000fa3609 [cctest] Clarify OverrideReadOnlyPropertyOnPrototype setup
The `readonly: true` key-value pair is redundant since it gets
ignored anyhow. This patch removes it.

Also, `configurable: false` is implied when
using `Object.defineProperty` (just like `enumerable: false`
and `writable: false`). Therefore, specifying only `configurable`
but not `enumerable` and `writable` gave the impression that
configurability was somehow the deciding factor for this test.
Instead, the only important data property for this test is
`writable: false`. This patch lists all four data property
attributes explicitly, making it clear that only `writable` has
a “special” value.
