This changes the logic for generating method names in `error.stack` to prepend an inferred type name only when the function name is a valid ECMAScript identifiers and does not equal the inferred type name, to (1) give developers more control over the exact name shown in `error.stack`, as well as (2) avoid confusion in the presence of renaming of local variables. Previously we'd leave the function name as-is if it was prefixed by the inferred type name, but that condition is unnecessarily strict, and led to a bunch of inconsistencies around special names like `<instance_member_initializer>` where this dynamic approached often prefixed it with the correct type name, but also sometimes got it wrong and prepended `Object.`, which is very unfortunate and misleading. Specifically for these special names, we'll add logic later in the parser to infer a useful (complete) name. The design doc (https://bit.ly/devtools-method-names-in-stack-traces) contains more background and examples of why we do this change.

V8 JavaScript Engine
V8 is Google's open source JavaScript engine.
V8 implements ECMAScript as specified in ECMA-262.
V8 is written in C++ and is used in Google Chrome, the open source browser from Google.
V8 can run standalone, or can be embedded into any C++ application.
V8 Project page: https://v8.dev/docs
Getting the Code
Checkout depot tools, and run
fetch v8
This will checkout V8 into the directory v8
and fetch all of its dependencies.
To stay up to date, run
git pull origin
gclient sync
For fetching all branches, add the following into your remote
configuration in .git/config
:
fetch = +refs/branch-heads/*:refs/remotes/branch-heads/*
fetch = +refs/tags/*:refs/tags/*
