In most cases where we bail out to TurboFan, we actually have a fallback
that just calls a C function instead. This fallback did not exist
initially, but was added later for other platforms (see e.g.
https://crrev.com/c/1044187).
By reusing that fallback on intel, we remove another portion of function
that could not be compiled in Liftoff on specific CPUs.

Individual frames of a stack frame in the frame cache might point
to the JSFunction of that corresponding stack frame. It is illegal to
serialize JSFunction objects in the isolate snapshot, so the attempt
to serialize the stack frame cache results in a crash. This can happen
when a warmup script is run, before a snapshot is created.
This CL fixes the crash by not utilizing the stack frame cache in case
the serializer is enabled.

We recently extended function-entry stack checks by an offset
representing the difference in optimized and unoptimized frame sizes,
with the intent of avoiding stack overflows during deopts. Although
the generated code is very efficient (just a single additional
register subtraction, executed exactly once per call), perf impact
is measurable.
To avoid the overhead in most cases, this CL adds a stack slack,
currently set to 256 bytes, by which deopts are allowed to exceed the
real V8 stack limit. For function-entry stack checks with an offset
less than stack slack, the offset is not applied and the more
efficient version of the stack check is emitted.
The V8 limit is chosen to be smaller than OS stack size (assumed to
be at least 1 MB). This guarantee is upheld even with slack.

Every time a JS function is called within a context that has a non-zero

As one of several steps involved in supporting struct-valued fields
within classes, this CL generates type verification code for the data
contained in those structs.
In order to generate verification code, Torque needs to know about
struct field offsets and the total size of structs. Those calculations
are added to StructType itself and the function TypeVisitor::ComputeType
which initializes the StructType. I repurposed the Field::offset value
to behave in structs more like it does in classes (it had previously
indicated the index of a field within a struct, but nobody used that
value). Overall this works okay, and I think it's less confusing to have
Field::offset mean the same thing everywhere. However, some struct
fields have types with unknown size (Field::GetFieldSizeInformation
fails), so those fields are now marked with offset Field::kInvalidOffset
to indicate that the structs containing them should not be used within
class fields or anywhere else that requires packed layout.

It was perhaps incorrectly not declared inline while still appearing in
the main header file and then appearing in the -inl.h. MSVC doesn't like
it being declared inline however, so just inline it directly into the
main header.

Currently it's pretty easy to write Torque code that generates an error
in some common generic function such as Convert<To: type, From: type>,
and unless your change is very small, it can be hard to figure out what
part of it caused that macro specialization. This CL updates the Torque
compiler to emit some extra information about the stack of code
positions that caused a specialization of a macro or builtin, similar to
what Clang does for C++ templates. Obviously there might be multiple
places that require a particular specialization, but we only report the
first one that caused the specialization to be created.

The constructor taking an Isolate and HeapObject never uses the
HeapObject value and just calls through to the Isolate constructor.

Still trying to find the culprit for https://crbug.com/893973,
which seems to be some internal inconsistency in the debug stack
trace iterator.
