The test says that it is testing dictionary mode, but it is only
creating fast mode arrays.

54d63acabf [ptr-compr][arm64] Finish introducing bottlenecks for accessing on-heap
tagged fields.

Implemented TurboAssembler::StoreTaggedField for tagged fields's store.
Instead of pushes like x64 does, in arm64 do loads due to doing a
load-poke combination rather than just a push.

See https://chromium-review.googlesource.com/c/v8/v8/+/1382740 for the x64
version.

2ef4e3d7f1 [ptr-compr][arm64] Introduce bottlenecks for accessing on-heap tagged fields.
This CL introduces TurboAssembler::LoadTaggedPointerField() and
TurboAssembler::LoadAnyTaggedField(), which respectively loads a field
containing a HeapObject, or any tagged value, and decompresses it if necessary.

486ec80a7d [parser] Reset expression_scope_ stack to nullptr when parsing a function body
That way we can properly walk the active ambiguous stack of expressions and
stop where it's non-ambiguous. In the bug we would have forced context
allocation of "this" in an outer function because an inner function was parsed
as part of an arrow function head and "this" was referenced. That caused the
ambiguous arrow head scope to be marked, even though the reference came from a
non-ambiguous function.

(Fixed test failure in lite-mode)

Introduce a PREMONOMORPHIC state to StoreGlobalIC

It's used rather narrowly for now -- only when we run into an
interceptor during the lookup. After the call to SetProperty, we know
more. That is, the interceptor was only there because it's a new
property, and the call to SetProperty ends up creating it.

By delaying the initialization of the IC, we recognize the (now)
created property, and can provide good feedback downstream to
TurboFan.

ed5230a996 improve exec performance on RegExp with named capture groups
When creating the results object for an exec call, V8 is calling into a
runtime helper once per named capture group. It can instead create that
object without any runtime calls, using existing CSA helpers. The only
additional cost of this approach is that it internalizes the capture
group names at regex compilation time, even if the script never calls
exec on that regex.

3724a12549 Reland "[error] extend error stack w/ function parameters"

Original change's description:
> [error] extend error stack w/ function parameters
>
> Extend FrameArray to hold weak references to parameters forfunctions in
> the call stack. The goal here is to provide more metadata for postmortem
> tools (such as llnode), especially in cases of rethrowing (this will be
> particularly useful when using postmortem with promises on Node.js).
>
> Besides postmortem, these changes allow us to print a more detailed
> stack trace for errors with parameters types (or even values), which can
> be useful since JavaScript functions can receive any number of
> parameters of any type, and having a function behave differently
> according to the number of parameters received as well as their types is
> a common pattern on JS libraries and frameworks.
