dec6dc4baf Prevent stack frame cache usage during isolate serialization
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.

4547c5ef30 [compiler] Allow deopts to slightly exceed the stack limit
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.

a3b5229bdd [wasm] Support stepping into Wasm from Javascript
We detect a stepping in Wasm from Javascript into Wasm then prepare
the target function for debugging.

The trick is redirect the target to interpreter and set a 'fake'
breakpoint in the first instruction. Currently we don't need to clear
this 'fake' breakpoint since it won't notify unless user intend to
step in.

db18e49556 PPC/s390: Add a debug v8 API SetDetachedWindowReason
Port 63dc55568b

Original Commit Message:

    A window is a Blink concept. This API marks the context as backing
    a detached window. This doesn't necessarily mean that the context is
    detached.

    Every time a JS function is called within a context that has a non-zero
    DetachedWindowReason, Runtime::kReportDetachedWindowAccess is invoked,
    which will report this call to Blink via a callback, which in turn can
    report number of such calls via UKM metrics.

88a2d01148 [torque] Verify nested struct fields in classes
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.

`ENABLE_SLOW_DCHECKS` attempts to use `std::iterator_traits` on the

the standard iterator member types were unavailable.
This adds these members.

2ad37be294 [objects] rename kSize to kHeaderSize for JSObject subclasses
For many subclasses of JSObject, we used kSize instead of kHeaderSize
even though they can contain in-object properties. In fact, kSize
was very much used as the header size, as can be seen in many examples
in this CL.

This change is a preparation for a for a cleanup of how Torque
generates field offsets.

80caf2cf53 [heap] Reduce size of possibly empty buckets
Before this CL a byte was used per bucket to store whether the bucket
is possibly empty or not. This CL changes this such that each bucket
only needs a single bit.

PossiblyEmptyBuckets is now a word in the page header. If more bits
are needed than fit into a single word, an external bitmap is
allocated using AlignedAlloc. Storing this on the page header, allows
to remove initial_buckets from the SlotSet. The SlotSet allocation is
then again a power-of-2 in release mode.

332290e46e [torque] Generate more detailed errors when instantiating generics
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.

84f3877c15 [cleanup] Split out bit-field.h and bounds.h from utils/utils.h
utils.h itself is fairly large and contains lots of unrelated functions
as well as having a fair number of dependencies itself, so this splits
bounds checking and bit field operations into their own headers in base
and replaces uses of utils.h with the more appropriate header where
possible. (Also fixes some cases where other headers were previously
brought in transitively).

6ec6ed9cbe Report real module in addition to fake scripts
Currently the inspector reports Wasm in one of two ways:
 - If there is a source map, report one script per Wasm script, with
   bytecode but no source.
 - If there is no source map, report one script per Wasm function, with
   source (Wasm disassembly) but no bytecode.

With this change, behavior with source map is same, but without source
map it will report both ways. This will allow us to change the frontend
to do its own disassembly, allowing us to remove the per-function scripts
in a future change.
