This migrates harness adjustments, to be loaded after mjsunit.js on
fuzzers for correctness fuzzing.

This is the first step adding deeper pretty printing. Other
adjustments will be added in follow ups.

AddCode and AddOwnedCode (from NativeModule), as well as the WasmCode
constructor are using a default value (false) for determining whether
the code is liftoff-compiled or not. This CL removes the default
value and requires each call to these functions/constructors to explicitly
set the value.

This is preparatory cleanup work for eventually tracking the functions
(rather than concrete closures) in the CALL_IC, also for builtins like
the default PromiseCapability [[Resolve]] and [[Reject]] functions. It
adds a new FeedbackCell type, which is used by JSFunctions consistently
now to reference the feedback vector (or undefined if not the function
is not compiled yet or is a native/asm.js function).

This also changes the calling convention for FastNewClosure builtin and
the JSCreateClosure operator in TurboFan to carry the FeedbackCell here
instead of the parent FeedbackVector and the slot index. In addition we
eliminate the now unused %InterpreterNewClosure runtime function.

This avoids generation of duplicate strings. Especially debug builds
suffer from this and generate 16000+ strings, mostly for CSA_ASSERT
and CAST statements. Deduplicating these trims that down to roughly
1000 strings.

Release builds are affected at a smaller scale. There, we have roughly
100 duplicate strings in the snapshot.

IterableToListCanBeElided checked that the input was always a HeapObject
but this is not true when an iterator symbol is defined on the Number
prototype, meaning Smi and HeapNumber can also be passed in.

Added a regression test for the crash and some correctness tests for
smi and double input to TA.from.

Also factored out the tests in typedarray-from.js that modify global
state e.g. protector cells, so that one iteration of the top level
loop does not interfere with the next.

Private fields should not return undefined on access miss, but instead
should throw a TypeError.

This patch uses a bit on v8::Symbol to mark if this symbol is a
private field or not.

This patch also changes the LookupIterator code path that deals with
LookupIterator::State::DATA to deal with JSReceiver instead of
JSObject.

Note: the error message doesn't output the field name, but that's a
