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.

Sparkplug is a new baseline, non-optimising second-tier compiler, designed to fit in the compiler trade-off space between Ignition and TurboProp/TurboFan.

This is the second reland of https://chromium-review.googlesource.com/c/v8/v8/+/2487122 , this time without RuntimeCallStats in the tests. Generalize the existing property lookup machinery (JSNCS::ReduceNamedAccess) to handle the case where the lookup_start_object and the receiver are different objects.
