This is a reland of
https://chromium-review.googlesource.com/c/v8/v8/+/2720300.
As compared to the original version, it adds
--no-stress-flush-bytecode to the const-dict-tracking.js test
Original description:
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 implements support for the case that the property
in question is an accesor, meaning that the given PropertyAccessInfo
has kind kAccessorDictionaryProtoConstant.

This feature will only be enabled if the build flag

This particular CL implements support for the case that the property
in question is a data property, meaning that the given
PropertyAccessInfo has kind kDataDictionaryProtoConstant.
Support for accessor properties is added in a separated CL.

For dictionary mode objects, whether or not a property is constant was
not tracked before. This CL makes the required non-Turbofan changes,
guarded behind the new flag V8_DICT_PROPERTY_CONST_TRACKING.
In addition, prototypes are not converted to fast mode objects if this
flags is enabled.
