This will enable Node.js to get much better performance from async_hooks
as currently PromiseHook delegates to C++ for the hook function and then
Node.js delegates it right back to JavaScript, introducing several
unnecessary barrier hops in code that gets called very, very frequently
in modern, promise-heavy applications.
This API mirrors the form of the original C++ function based PromiseHook
API, however it is intentionally separate to allow it to use JSFunctions
triggered within generated code to, as much as possible, avoid entering

Because PromiseHook has internal use also, beyond just the Node.js use,
I have opted to leave the existing API intact and keep this separate to
avoid conflicting with any possible behaviour expectations of other API
users.
The design ideas for this new API stemmed from discussion with some V8

It could happen (e.g. with --stress-background-compile) that the main
thread blocks for a background thread but the background thread requests
a GC from the main thread. This would result in a deadlock. Avoid this
by parking the main thread for potentially blocking operations and allow
allocations while the main thread is parked.
This CL introduces new states for the main thread: CollectionRequested
and ParkedCollectionRequested. These states will force Safepoint(),
Park() and Unpark() on the main thread into slow paths. The slow path
can then perform a GC on the main thread - right before parking or after
the main thread got unparked.

AddImmediate ends up pushing repeated immediates very often
unecessarily. Add support for Int64 immediates being inlined into
InstructionOperand if they fit into the payload (which is almost always
the case). Also add a seperate rpo_immediate vector for RPO numbers to
avoid having to add them to the immediates_ vector multiple times.
Ideally the RPO values would also be inlined, however JumpThreading
needs to patch RPO targets throughout the instruction stream, so we
need an indirection.

shortens the runtime of further tests.
Original description:
This CL is part of a series that adds the C++ implementation of
SwissNameDictionary, a deterministic property backing store based on
Swiss Tables.
This CL adds the actual tests for SwissNameDictionary, defined in
test-swiss-name-dictionary-shared-tests.h, using the infrastructure
in test-swiss-name-dictionary-infra.[h|cc].

LiftoffCompiler::ProcessParameter assumed that by processing parameters
in the order of their index, register parameters get
processed first, and that for processing stack parameters it can already
use all registers as temp registers. This is not true with reference
type parameters, because registers always first get assigned to value
type parameters even when there is a reference type parameter with a
lower index. Because of this incorrect assumption register parameters
were overwritten by reference type parameters on the stack that got
processed first.
With this CL, only those registers get used as temp registers for
reference type parameters that are not used for parameters.

Take into account that the implicit rethrow at the end of a try block
might unpack the exception values, and reserve enough stack space for
them.
This is normally done for all throwing opcodes before the switch, but
'end' is not considered a throwing opcode, which is why it needs special
handling.
Also clean up by factorizing the rethrow logic.

This reverts commit c85b7a449d.
This reland fixes missing serialization of objects stored in
CallHandlerInfo::data by adding necessary handling of these objects
in FunctionTemplateInfoRef::SerializeCallCode when running with
direct heap access.
Drive-by: Remove declaration of CallHandlerInfoRef::Serialize, which
did not have a definition.
Original change's description:
> [TurboFan] Move FunctionTemplateInfo to never serialized
>
> This CL moves FunctionTemplateInfo to the list of never serialized
> objects, allowing direct heap reads. To make this threadsafe, the CL:
> - adds necessary atomic (relaxed/acquire-release) operations to the
> accessors of FunctionTemplateInfo.
> - changes FunctionTemplateInfoRef::LookupHolderOfExpectedType to be
> usable from the background thread (e.g. no handle construction) with
> the caveat of skipping optimization in some cases where necessary
> JSObjects are not serialized.
>
> Drive-by: Add missing serialization of objects possibly reachable
> through CallHandlerInfo::data.
