Original commit message:
[objects] Move functions to inline headers
This moves a series of functions from dictionary.h and hash-table.h
to resp. dictionary-inl.h and hash-table-inl.h.
The functions that were moved all somehow use other functions that
are defined in -inl.h files.
This change fixes the Node.js Windows builds.

Original commit message:
Make SetSyntheticModuleExport throw instead of crash for nonexistent export name
Per spec, Module::SetSyntheticModuleExport should throw a ReferenceError
when called with an export name that was not supplied when constructing
that SyntheticModule. Instead, the current implementation crashes with
a failed CHECK().
Add a new Module::SyntheticModuleSetExport that throws (without an ensuing
crash) for this case, and deprecate the old
Module::SetSyntheticModuleExport.

Original commit message:
[api] Add possibility for BackingStore to keep Allocator alive
Add an `array_buffer_allocator_shared` field to the
`Isolate::CreateParams` struct that allows embedders to share
ownership of the ArrayBuffer::Allocator with V8, and which in
particular means that when this method is used that the
BackingStore deleter will not perform an use-after-free access to the
Allocator under certain circumstances.
For Background:
tl;dr: This is necessary for Node.js to perform the transition to
V8 7.9, because of the way that ArrayBuffer::Allocators and their
lifetimes currently work there.
In Node.js, each Worker thread has its own ArrayBuffer::Allocator.
Changing that would currently be impractical, as each allocator
depends on per-Isolate state. However, now that backing stores
are managed globally and keep a pointer to the original
ArrayBuffer::Allocator, this means that when transferring an
ArrayBuffer (e.g. from one Worker to another through postMessage()),
the original Allocator has to be kept alive until the ArrayBuffer
no longer exists in the receiving Isolate (or until that Isolate
is disposed). See [1] for an example Node.js test that fails with
V8 7.9.
This problem also existed for SharedArrayBuffers, where Node.js
was broken by V8 earlier for the same reasons (see [2] for the bug
report on that and [3] for the resolution in Node.js).
For SharedArrayBuffers, we already had extensive tracking logic,
so adding a shared_ptr to keep alive the ArrayBuffer::Allocator
was not a significant amount of work. However, the mechanism for
transferring non-shared ArrayBuffers is quite different, and
it seems both easier for us and better for V8 from an API standpoint
to keep the Allocator alive from where it is being referenced.
By sharing memory with the custom deleter function/data pair,
this comes at no memory overhead.

GCC: explicitely instantiate JSObject::ApplyAttributesToDictionary for NumberDictionary
elements.cc invokes ApplyAttributesToDictionary using NumberDictionary as its template
parameter. But the declaration of the template method is in js-object.cc, so nobody
can actually compile the version for number dictionary. This is fixed requesting
explicit instantiation for NumberDictionary.
This was breaking GCC build.

[ptr-compr][ubsan] Use [Read/Write]UnalignedValue for unaligned fields
When pointer compression is enabled the [u]intptr_t and double fields are
only kTaggedSize aligned so in order to avoid undefined behavior in C++ code
we have to access these values in an unaligned pointer friendly way although
both x64 and arm64 architectures (where pointer compression is supported)
allow unaligned access.
These changes will be removed once v8:8875 is fixed and all the
kSystemPointerSize fields are properly aligned.

Original commit message:
[heap] Clean-up some weak map entries in scavenger
This change enables clean-up of weak map entries in the
scavenger of the weak map is in the young generation.
With this change, the scavenger treats keys in ephemerons as
weak instead of strong, but does not implement full ephemeron
semantics: Values are treated always as strong, independently
of whether the key is live or not.
This approach ensures that no value is cleaned up accidentally.
After scavenging, all entries with dead keys are removed from
weak maps. After that, some values that are not referenced anywhere
anymore might still be in the heap, and those can be cleaned up
in the next scavenge.
What the scavenger does, amounts to one iteration of the
fixed-point algorithm required to implement ephemeron semantics.
We hope that this is a reasonable trade-off between time spent
tracing and cleaned-up entries.
This change does not affect weak maps that reside in old space.

Original commit message 9365d09:
[coverage] Rework continuation counter handling
This changes a few bits about how continuation counters are handled.
It introduces a new mechanism that allows removal of a continuation
range after it has been created. If coverage is enabled, we run a first
post-processing pass on the AST immediately after parsing, which
removes problematic continuation ranges in two situations:
1. nested continuation counters - only the outermost stays alive.
2. trailing continuation counters within a block-like structure are
removed if the containing structure itself has a continuation.

Original commit message aac2f8c:
[coverage] Filter out singleton ranges that alias full ranges
Block coverage is based on a system of ranges that can either have
both a start and end position, or only a start position (so-called
singleton ranges). When formatting coverage information, singletons
are expanded until the end of the immediate full parent range. E.g.
in:
{0, 10} // Full range.
{5, -1} // Singleton range.
the singleton range is expanded to {5, 10}.
Singletons are produced mostly for continuation counters that track
whether we execute past a specific language construct.
Unfortunately, continuation counters can turn up in spots that confuse
our post-processing. For example:
if (true) { ... block1 ... } else { ... block2 ... }
If block1 produces a continuation counter, it could end up with the
same start position as the else-branch counter. Since we merge
identical blocks, the else-branch could incorrectly end up with an
execution count of one.
We need to avoid merging such cases. A full range should always take
precedence over a singleton range; a singleton range should never
expand to completely fill a full range. An additional post-processing
pass ensures this.

Original change's description:
> [coverage] change block range to avoid ambiguity.

> By moving the block range end to left of closing bracket,

Introduce ScriptOrModule and HostDefinedOptions
This patch introduces a new container type ScriptOrModule which
provides the name and the host defined options of the script/module.
This patch also introduces a new PrimitivesArray that can hold
Primitive values, which the embedder can use to store metadata.
The HostDefinedOptions is passed to V8 through the ScriptOrigin, and
passed back to the embedder through HostImportModuleDynamically for
module loading.
