The trace_event_common.h header file isn't used with Perfetto any

v8_tracing should be a public dependency so that any public headers

This CL is part of a series that implements Turbofan support for
property accesses satisfying the following conditions:
1. The holder is a dictionary mode object.
2. The holder is a prototype.
3. The access is a load.
This feature will only be enabled if the build flag
v8_dict_property_const_tracking is set.
This particular CL modifies existing mjsunit tests whose assumptions
don't hold if v8_dict_property_const_tracking is enabled. This is
done by adding special handling for the case that
%IsDictPropertyConstTrackingEnabled() holds.

Due to immutable loads being placed earlier during scheduling and

significantly. Until we implement an optimization to avoid spilling in

Remove the requirement to pass the native context into the script cache,
simple to be able to access the empty function. Instead, for script
cache keys, use Smi::zero() in the 'owner function' slot.
This allows CompileUnboundScript to be called outside of a Context

Before the introduction of exception handling in the compile fuzzer,
stack overflows were deterministic because they always caused the whole
stack to be unwound.
With support for exception handling, the stack overflow exception can be
caught and is a source of nondeterminism. Flag the interpreter result as
such in this case so that we skip the correctness check.
