We only care about huge functions (>100kB) as they can cause extended
compilation times and OOM situations. These are difficult to see in the
existing histogram as they only account for a tiny fraction of functions.
We therefore introduce a new counter that only covers those functions
and remove the other histogram.

In GetOwnFastDataPropertyFromHeap, we read a property value
then compare it with the expected representation. We already
had code to bail out of that particular optimization if there
was a mismatch, however it missed the case of expected
representation being a HeapObject, and when a Smi value was found.
The fix is to use the excellent pre-existing method
Object::FitsRepresentation() to make this check. Thusly, all
cases are handled.

TurboFan reads the value in HeapNumber, and TSAN detects a data
race between this read and sets on the main thread elsewhere.
We mark this as relaxed atomic (meaning, correct value of the read
is not guaranteed). The compiler uses the dependency mechanism
to re-read the value safely on the main thread later, and aborts
compilation if a change is detected.

This CL adds support for updating code objects. So far code objects
were immutable. Sparkplug makes compilation a very frequent operation
and thus wants to avoid copying the instruction stream from the
AssemblerBuffer into the code object (with more overhead that entails).
The idea is to allocate an "empty" Code object initially, which is
likely large enough to hold the full instruction stream. Then Sparkplug
will compile the given function and write the instruction stream
directly into the code object. After compilation is done Sparkplug trims
the Code to the right size and finishes its initialization.
We use relocation_info to determine whether a Code object is fully
initialized: undefined means that this object is filled by SparkPlug
at the moment. If it's a proper ByteArray, this code object is assumed
to be initialized. Turbofan still fully initializes the Code object
immediately.
Before changing the size of the code object, EnsureSweepingCompleted()
makes sure that the code object's page is swept already. This prevents
that the concurrent sweeper loads the new and smaller object size and
stores that memory in the free list.
NotifyCodeObjectChanged() signals the GC that the code object is now
fully initialized and revisits that object (even if it is black already)
to find and record outgoing references in the instruction stream.

In order to implement eager (side effect free) evaluation of arbitrary
accessor properties correctly, we need the ability to call getters while
guaranteeing that we don't trigger side effects. This is accomplished by
adding a `throwOnSideEffect` flag to the `Runtime.callFunctionOn` API,
similar to what's already available with the `Runtime.evaluate` and the
`Debugger.evaluateOnCallFrame` APIs.

A frame state's outer frame state input can be kDeadValue. A DCHECK
did not take that into account. In release builds there was no issue
because we branch on the opcode anyways.
While fixing this bug, I'm strengthening the FrameState class such that
a FrameState node must have a kFrameState operator. I'm also
- changing the result type of outer_frame_state() from FrameState to
Node* since it may in fact not be a kFrameState;
- removing has_outer_frame_state() because I find it unintuitive to
have outer_frame_state() return non-NULL even when
has_outer_frame_state() would return true.

For very large snapshots, calculating the checksum of the snapshot can
take at least 30% of the time to deserialize the snapshot, so add a flag
to skip it.

Commit 26d85acee2 "Use IMMEDIATE_CRASH on
official build FATAL errors." has changed how FATAL macro behaves on
such builds. Unfortunately this affects logging and
random number generator v8 unittests which use ASSERT_DEATH_IF_SUPPORTED
macro. After the change we no longer get any v8 CHECK crash messages on
official builds thus failing those tests.
Fix this by adjusting failing test expectations to reflect the new,
expected results v8 now has on official builds.

Print the reference stack when V8 is unable to encode an external
reference in debug builds so that it's easier for the embedder
to track the external reference down.
