Don't switch to the catch state if it is never reached.
Also steal the catch state instead of splitting it since it cannot be

With the addition of deoptimizing to baseline, we mark the begin of
every bytecode as a valid jump target in baseline code (Required for
CFI on arm64).
Therefore we can omit marking excpetion handler positions and binds
at the beginning of the bytecode as valid jump targets now.

In inspector-task.cc, the frontend and backend runners are explicitly
joined before going out-of-scope. On POSIX platforms, calling
pthread_join() on a thread that has already been joined has undefined
behavior. For example, under the musl C runtime library, a successful
call to pthread_join() will unmap the pthread_t thread information
region, and calling pthread_join() again will result in SIGSEGV.

AddImmediate ends up pushing repeated immediates very often
unecessarily. Add support for Int64 immediates being inlined into
InstructionOperand if they fit into the payload (which is almost always
the case). Also add a seperate rpo_immediate vector for RPO numbers to
avoid having to add them to the immediates_ vector multiple times.
Ideally the RPO values would also be inlined, however JumpThreading
needs to patch RPO targets throughout the instruction stream, so we
need an indirection.

these, if supported, when handling a Select expression in the wasm
graph builder. FlagsContinuation have been modified to support the
select operation and code generation support has been added for arm64.
This improves the 'Bullet' physics benchmark by ~2-3%.

Instead of assigning serial numbers when the template infos are
created, this patch creates serial numbers only when they are added to
cache.
This way only the ones that are first instantiated are allocated the
fast template cache. Previously, various accessors and methods that
would almost never get instantiated got assigned to the fast template
cache.

This reverts commit c10aa432b8.
Reason for revert: https://ci.chromium.org/ui/p/chromium/builders/try/mac-rel/b8851806981073807856/overview
Original change's description:
> [sparkplug] Enable short builtin calls by default
>
> ... when they are enabled via the GN flag.
>
> Also disable this optimizaion for CFI builds for now.
>
> Sheriffs: This CL adds ~1.2-1.4Mb of memory overhead per Isolate on
> certain configurations and that's expected. This is a temporary fix
> until the full solution is implemented.
> See the design doc linked to the issue for details.
