This method used to be defined on Object and handled Strings and
JSObjects; but only the object hierarchy rooted at JSObject has
'elements', and Strings are handled slightly differently. Thus it
makes sense to split up into
JSObject::GetOwnConstantElement
String::GetCharAsString
This way, we can also separate future work on making JSObjects and
Strings never-serialized.

Currently if gn check is enabled (with v8/third_party ignored), there
are many errors due to headers being used without adding the proper
dependency in BUILD.gn (or because it's being used transitively without
a public_deps chain).
This makes the number of errors go from 2114 to 195.
Apart from adding dependencies, it also moves _v8_internal_Node_Print
from objects-printer.cc to node.cc so it can see the Node::Print method
which wouldn't otherwise be possible without a circular dependency. Also
removes the previously deleted compiler/graph-builder-tester.h file.

Earlier we used the same interrupt budget always and waited for higher
number of ticks when tiering up from Turboprop to TurboFan. On some of
the real world pages this adds a reasonable overhead for processing
these interrupts. This cl sets the interrupt budget to a higher value so
there are fewer interrupts. This cl:
1. Sets the interrupt budget on feedback cell to
FLAG_interrupt_budget * scale factor when we install optimized code.
2. Resets the budget to FLAG_interrupt_budget when there is a
deoptimization.
3. Updates the runtime profiler to remove the scaling of number of ticks
needed for optimization when tiering up from TP to TF.
On sheets benchmark, we spend 40-50ms when servicing interrupts from
Turboprop code. This change brings it down to ~7ms. We also see
improvements on other pages.

This is a reland of 76a2ab06a1
Changes since the original CL:
- Handle unserialized elements (optional result in getter).
- Merge should_access_heap and --turbo-direct-heap-access paths.
- Slightly update the serialized path in GetOwnCowElement.
- Fix the cctest, add a regression test.
Atomic JSObject::elements/JSArray::length setters are addressed
in this CL: crrev.com/c/2704076.
Original change's description:
> [compiler] Direct heap reads for JSArrayRef
>
> There are two aspects to the non-JSObject parts of JSArrayRef:
>
> - JSArrayRef::length. Relevant only in two spots, 1. when reading
> (immutable) array boilerplates and 2. for GetOwnCowElement.
>
> - JSArrayRef::GetOwnCowElement. May read into a copy-on-write backing
> store. Relies on the invariant that cow backing stores are immutable.
>
> This CL renames the length accessor to length_unsafe to make the
> danger explicit at callsites.
>
> For GetOwnCowElement the refactor is slightly larger, since we now
> need to read into the backing store while keeping full control of
> object reads (e.g. JSArray::length and JSArray::elements_kind). We
> make all reads explicit at the call site by requiring that elements,
> elements kind, and length are passed in as arguments to
> GetOwnCowElement. Inside GetOwnCowElement, consistency between these
> is *not* guaranteed due to concurrency. At runtime, consistency *is*
> guaranteed through the reference-equality check on the elements seen
> during compilation. The actual elements read is implemented in
> ConcurrentLookupIterator::GetOwnCowElement.

This CL introduces a test runner flag to detect if webassembly has been
disabled. Since all tests that require wasm are alrady skipped in
lite mode, we introduce a has_webassembly flag for the test runner which
checks for v8_enable_webassembly=true and v8_enable_lite_mode=false.
As a drive-by, we also do not set the V8_ENABLE_WEBASSEMBLY
preprocessor flag if lite mode is enabled.
The status files are updated by splitting wasm tests from the
"lite_mode" section and checking for "not has_webassembly" instead.
Note that the v8_enable_webassembly=false configuration is not tested
on any bot currently, but I will make sure that all tests keep passing
on further changes in this configuration.

Whenever we destroy an object that contains a
(Weak)(CrossThread)Persistent, we call the Persistent's dtor which frees
the relevant PersistentNode. To get the PersistentRegion for the node,
we get the value, then get the the relevant page which holds a reference
to the heap which holds the regions.
During a termination GC there is no marking and no weak callback
processing. That means that, when destroying a Persistent, the page on
which the object referenced by the Persistent resides may have already
been swept and destroyed. Then when we try to get the page we cleared or
unallocated memory and crash.
This issue presented as a sweeper crash in the web tests and
content_browsertests.
This issue affects only Weak(CrossThread)Persistent since the region for
their strong counterparts are already cleared at the start of a
termination GC.
This is not an issue in the Blink impl because (1) Blink finds the
elevant regions through ThreadState without going through pages, and
(2) Blink runs a full GC on termination that includes executing weak
callbacks.
Alternatively we could trace the Weak(CrossThread)Persistent region
which will run the weakness callbacks and clear all WeakPersistents.
The cost and outcome is equivalent.

Thereby the memory can grow in-place. On 32-bit platforms, however, we
allocate only the initial size, and grow the memory by reallocating the

big. With this CL we allow to reserve 1GB of memory even on 32-bit

Code objects are exposed through JSFunction and SharedFunctionInfo.
If they are builtins, we don't have to worry about background threads
seeing partially initialized code objects. If they are optimized code
objects, we may. Background threads read the code fields with
AcquireLoad semantics. The fields are set on the main thread with
ReleaseStore semantics when appropriate.
Special care is taken when setting an optimized code object in a closure
in the interpreter entry stub. Since the MacroAssembler doesn't support
ReleaseStore semantics, this CL ensures that the optimized code object
is stored with those semantics in the feedback vector, where the
interpreter entry stub finds it.
