We added this to add elements kind to handlers so Turboprop could
use the elements kind information for inlining array builtins when using
dynamic map checks. This information isn't useful without other map
based optimizations like constant folding to inline array builtins.
So we don't need this information.

This CL adds partial support for objects whose slow mode dictionaries
are OrderedNameDictionaries. This is the case for all slow mode objects
if V8_DICT_MODE_PROTOTYPES is enabled.

Specifically, this CL contains minor changes to CSA code, short of
actually performing ordered dictionary lookups using CSA
implementations of these lookups.

The basic block instrumentation currently uses 32-bit integers, which
could overflow during a long profiling session. I considered upgrading
them to 64-bit integers, but generating the correct instrumentation code
for various architectures would be rather non-trivial. Instead, this
change uses 64-bit floating-point values, which are simple and also have
the nice behavior that they saturate rather than overflowing.

Even though e.g. {BranchExpectTrue} could become useful again in the

Deserialization is currently split into three main steps:
1) Read code and allocate code buffer
2) Copy and relocate code
3) Publish

This moves step 2) to a background task so that it can concurrently
process work units added to the work queue by step 1).

Next, step 3) will also be moved to a background task to create a full
pipeline, such that we can start publishing the first units almost
immediately.

This CL adds tracing scopes for the various cppgc classes.
Scopes use TRACE_EVENT_BEGIN and TRACE_EVENT_END macros to report trace
events. To do so they need to include trace-event.h. For unified heap
builds, trace-event.h forwards to v8's src/tracing/trace-event.h. For
other builds, trace-event.h provides a subset of
src/tracing/trace-event.h that covers just the parts used by cppgc.

This CL covers what we need for traces and blink gc metrics (up to
renaming events from BlinkGC.* to CppGC.*). UMA and UKM are not yet
handled.
