commit ce71348a09f6689dd01a68db64b172191d0182d8
Author: Andrey Kosyakov <caseq@chromium.org>
Date: Thu Dec 21 18:38:38 2023 +0000
[bindings] Use v8::Array::Iterate for converting script wrappables
This changes CreateIDLSequenceFromV8Array to use the new
v8::Array::Iterate() operation.
This speeds up the "execBundles" part of the microbenchmark
at crbug.com/dawn/1858 by around 3x.
This depends on crrev.com/c/4846594 landing (and rolling) first.
This is a slight re-work of https://crrev.com/c/4847447/3,
originally by jkummerow@chromium.org
Bug: v8:14218, dawn:1858, 1511239

commit 940af9f2c87b436559b97c53763aa9eaaf1254eb
Author: Jeremy Roman <jbroman@chromium.org>
Date: Wed Nov 15 16:24:54 2023 +0000
Use C++20 features to simplify blink::NativeValueTraitsBase.
These allow some of the metaprogramming bits to be simplified a little.

commit 940af9f2c87b436559b97c53763aa9eaaf1254eb
Author: Jeremy Roman <jbroman@chromium.org>
Date: Wed Nov 15 16:24:54 2023 +0000
Use C++20 features to simplify blink::NativeValueTraitsBase.
These allow some of the metaprogramming bits to be simplified a little.
