super.property` should resolve super in the current scope, not C's

TypedArray copyWithin/fill should throw in that condition. TypedArray

%TypedArray.prototype% methods that receive a user callback
fn should not break in the mid-way of the iteration when the
backing array buffer was been detached. Instead, the iteration
should continue with the value set to undefined.
Notably, %TypedArray.prototype%.filter was throwing when the
backing buffer was detached during iteration. This should not

The revert was at crrev.com/c/2996198.
Changed: Fixed a test in which bytecode flushing caused a behavioral
change between serialized- and unserialized SFI Refs. The serialized
SFI ref kept bytecode alive while unserialized SFIs allow flushing.
The test was fixed by adding a %PrepareFunctionForOptimization
annotation.

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.

This flag enables feedback allocation heuristics to be based on the
function size. The threshold for feedback allocation is set to
12 * bytecode size to roughly mimic the allocation after 12 invocations.
We tried 4 * bytecode size earlier and there were few memory regressions
on real world pages. Speedometer improved by ~1% [1, 2]. This time
trying with a higher factor this time to see if we still have
speedometer improvements without any memory regressions.

Currently, feedback vectors are allocated on a fixed budget of 1024.
In some cases it might be beneficial to allocate feedback vectors based
on invocation count rather than fixed budget. For example, if we have
a large function that is only run once. This cl adds an option to
use interrupt budget based on the bytecode size. It kind of mimics
invocation count. We would allocate feedback vectors early when we
have loops which is also required.
This flag is turned off by default. In followup cl, we will enable it
and if the memory / performance tradeoff is good we might make it
default.

With non-super loads (receiver == lookup_start_object), we don't hit
the code in AccessorAssembler::GenericPropertyLoad calling
CSA::TryGetOwnProperty if the receiver (the lookup_start_object) is a
SMI.
But with super property loads, if we set up lookup_start_object the
right way, we will hit this code.
The code was assuming receiver is a HeapObject, which is too
restrictive. The receiver is only used for the accessor call, so
it's ok to make the type more generic.
