The per-isolate compilation cache is a lot faster still than
the serialized code cache. Promote code to compilation cache

The CL enables the same instructions are selected for Word32 and Word64 compare
operations which is possible due to a fact 32-bit inputs and produced values
are always sign-extended.

This makes the Isolate::Throw logic not depend on a prediction of
whether an exception is caught or uncaught. Such a prediction is
inherently undecidable because a finally block can decide between
consuming or re-throwing an exception depending on arbitray control
flow.
There still is a conservative prediction mechanism in place that
components like the debugger or tracing can use for reporting.
With this change we can get rid of the StackHandler::kind field, a
pre-requisite to do table-based lookups of exception handlers.

Increased rate of Chrome crashes. Requires further investigation.
Original issue's description:
> Reland of Remove slots that point to unboxed doubles from the StoreBuffer/SlotsBuffer.
>
> The problem is that tagged slot could become a double slot after migrating of an object to another map with "shifted" fields (for example as a result of generalizing immutable data property to a data field).
> This CL also adds useful machinery that helps triggering incremental write barriers.

Remembering the current branch is a relic from the past
where no work-dir checkout was used. Now this doesn't give
much benefit and screws up the script if it was left in
a bad state (e.g. after a master restart).

Error.stack contains function.name if its type is string.
Otherwise if function have inferred name then .stack contains it.
For functions from eval .stack property contains "eval".

Since incremental marking hasn't completed yet at this point, we can't
use the MC's root visitor.
Also, we shouldn't hurry with incremental marking while

set_target_internal_reference accordingly to distinguish between
