Bump V8 from 15.5.35.7 to 15.6.75 and rebase our V8 patches onto
it. Extend 0043 to also disable metagen instance types in the Bazel
build, since V8 15.6 enables them by default.
Since V8 15.6, new Function() with no arguments passes isCodeLike =
false to the code generation callback, and V8 also reports each
object argument before converting it to a string. The empty-function
allowance in modifyCodeGenCallback therefore now matches on the exact
synthesized source alone. setup-test covers new Function(''), which
is now allowed, and an object argument, which stays blocked.
V8 15.6 deprecates FunctionCallbackInfo::Data() in favor of
DataV2(), which returns a v8::Data. Switch our callbacks to
DataV2().As<v8::Value>(), since clang-tidy treats the deprecation
warning as an error.
V8 15.6 also deprecates the V2 continuation-preserved embedder data
accessors, which are now plain aliases. Call the unsuffixed
Get/SetContinuationPreservedEmbedderData() instead.
Standard API audit: V8 15.6.75 enables no new standard API by
default, so this update disables none and needs no compatibility
flag. V8's shipped feature list (src/flags/feature-flags.h) gains
only homomorphic_ic, an internal IC optimization. Wasm
wide_arithmetic moves from pre-staged to staged and stays off. No
flag default changes to enable a feature, and
src/init/bootstrapper.cc and src/builtins/builtins-definitions.h are
unchanged from 15.5.35.7. The only newly installed function,
Sandbox.getMetadata, belongs to V8's sandbox testing API, which
workerd does not enable. Import text shipped before 15.6 and stays
disabled with --nojs-import-text.
Generated by the V8 nightly (ci/v8-nightly).
