Since FallThruTo is often followed by PopControl, we can save a few cache state copy operations in Liftoff by merging the two. On epic workloads, this saves ~18% of Steal operations and ~22% of Split operations.

This fixes a bug from 0400fc20, which assumed that we can set the markbits and the marked descriptors counter independently. This does not work because the Scavenger skips slots recording for non-black promoted objects. The fix is to mark the descriptor array black whenever we change the marked descriptors counter.

The DCHECK was overly restrictive when checking that a weak handle is not a finalizer when hitting it through a regular scavenge processing path. Only happened with finalizers to unmodified API wrappers or regular objects that were also marked as independent.

This CL makes several changes to bootstrapper to reduce code verbosity: - Adds an InstallToStringTag helper and uses it everywhere (while removing now-redundant comments). - Reduces explicit calls to Factory::InternalizeUtf8String by adding some overloads of helpers and of JSObject::AddProperty. - Uses InstallConstant in all applicable cases. - Removes attributes arguments when all callers pass DONT_ENUM.

Avoid named constructors for Value and Control and the hack to also have them on subclasses. Instead, add a new template type and a constructor to create the subtype from this template. Instead of the named constructors on the subtype, we now create a template and initialize the subtype from the template.

Clemens Hammacher authored
Forgetting V8_NOEXCEPT annotations on copy constructors, move constructors, copy assignment operators or move assignment operators can cause subtle performance bugs or compilation failures, sometimes only on specific architectures or compilers. Thus check that all those special class members are marked V8_NOEXCEPT. This check is only executed on modified files for now, and can be bypassed. Please report any false positives on the associated bug.
